Search Worlds Without End

After thousands of years searching, humans stand on the verge of first contact with an alien race. Two human groups: the Qeng Ho, a culture of free traders, and the Emergents, a ruthless society based on the technological enslavement of minds.

The group that opens trade with the aliens will reap unimaginable riches. But first, both groups must wait at the aliens' very doorstep for their strange star to relight and for their planet to reawaken, as it does every tow hundred and fifty years....

Then, following terrible treachery, the Qeng Ho must fight for their freedom and for the lives of the unsuspecting innocents on the planet below, while the aliens themselves play a role unsuspected by the Qeng Ho and Emergents alike.

More than just a great science fiction adventure, A Deepness in the Sky is a universal drama of courage, self-discovery, and the redemptive power of love.

Six days ago, astronaut Mark Watney became one of the first people to walk on Mars.

Now, he's sure he'll be the first person to die there.

After a dust storm nearly kills him and forces his crew to evacuate while thinking him dead, Mark finds himself stranded and completely alone with no way to even signal Earth that he's alive—and even if he could get word out, his supplies would be gone long before a rescue could arrive.

Chances are, though, he won't have time to starve to death. The damaged machinery, unforgiving environment, or plain-old "human error" are much more likely to kill him first.

But Mark isn't ready to give up yet. Drawing on his ingenuity, his engineering skills—and a relentless, dogged refusal to quit—he steadfastly confronts one seemingly insurmountable obstacle after the next. Will his resourcefulness be enough to overcome the impossible odds against him?

The man on the moon was dead. They called him Charlie. He had big eyes, abundant body hair, and fairly long nostrils. His skeletal body was found clad in a bright red spacesuit, hidden in a rocky grave. They didn't know who he was, how he got there, or what had killed him. All they knew was that his corpse was fifty thousand years old -- and that meant this man had somehow lived long before he ever could have existed.

At first, only a few things are known about the celestial object that astronomers dub Rama. It is huge, weighing more than ten trillion tons. And it is hurtling through the solar system at inconceivable speed. Then a space probe confirms the unthinkable: Rama is no natural object. It is, incredible, an interstellar spacecraft. Space explorers and planet-bound scientists alike prepare for mankind's first encounter with alien intelligence. It will kindle their wildest dreams... and fan their darkest fears. For no one knows who the Ramans are or why they have come. And now the moment of rendezvous awaits -- just behind a Raman airlock door.

Stephen R. Donaldson's thrilling Gap series--The Real Story, Forbidden Knowledge, A Dark and Hungry God Arises, and Chaos and Order--introduced us to an adventure as vast as the galaxy and unpredictable as the human heart. It is the work of a storytelling genius with more than ten million copies of his books in print worldwide. Now in this dark, intense story, Donaldson delivers the thrilling conclusion to one of the most powerful science fiction stories ever told.

The countdown has begun. The battleworn crew of Trumpet is in disarray, as they attempt to pursue the pirate ship Soar and her captain Sorus Chatelaine. With one crew member infected by the Amnion and another stranded in the vacuum of space, all their hopes lie with Angus Thermopyle, once a bloodthirsty pirate, now a cyborg working against his will for the United Mining Companies Police--the strongest, most rapacious force in all of human space. As Angus, Morn Hyland, and her force-grown son Davies race for home across the vast reaches of forbidden space, they have no way of knowing that the final confrontation between Warden Dios and The Dragon has begun. Or that the fate of all humankind hangs in the balance.

Two months since the stars fell...

Two months since sixty-five thousand alien objects clenched around the Earth like a luminous fist, screaming to the heavens as the atmosphere burned them to ash. Two months since that moment of brief, bright surveillance by agents unknown.

Two months of silence, while a world holds its breath.

Now some half-derelict space probe, sparking fitfully past Neptune's orbit, hears a whisper from the edge of the solar system: a faint signal sweeping the cosmos like a lighthouse beam. Whatever's out there isn't talking to us. It's talking to some distant star, perhaps. Or perhaps to something closer, something en route.

So who do you send to force introductions on an intelligence with motives unknown, maybe unknowable? Who do you send to meet the alien when the alien doesn't want to meet?

You send a linguist with multiple personalities, her brain surgically partitioned into separate, sentient processing cores. You send a biologist so radically interfaced with machinery that he sees x-rays and tastes ultrasound, so compromised by grafts and splices he no longer feels his own flesh. You send a pacifist warrior in the faint hope she won't be needed, and the fainter one she'll do any good if she is. You send a monster to command them all, an extinct hominid predator once called vampire, recalled from the grave with the voodoo of recombinant genetics and the blood of sociopaths. And you send a synthesist-an informational topologist with half his mind gone-as an interface between here and there, a conduit through which the Dead Center might hope to understand the Bleeding Edge.

You send them all to the edge of interstellar space, praying you can trust such freaks and retrofits with the fate of a world. You fear they may be more alien than the thing they've been sent to find.

But you'd give anything for that to be true, if you only knew what was waiting for them...

We are not alone.

The alien protomolecule is clear evidence of an intelligence beyond human reckoning. No one knows what exactly is being built on Venus, but whatever it is, it is vast, powerful, and terrifying.

When a creature of unknown origin and seemingly impossible physiology attacks soldiers on Ganymede, the fragile balance of power in the Solar System shatters. Now, the race is on to discover if the protomolecule has escaped Venus, or if someone is building an army of super-soldiers.

Jim Holden is the center of it all. In spite of everything, he's still the best man for the job to find out what happened on Ganymede. Either way, the protomolecule is loose and Holden must find a way to stop it before war engulfs the entire system.

CALIBAN'S WAR is an action-packed space adventure following in the footsteps of the critically acclaimed Leviathan Wakes.

Gateway opened on all the wealth of the Universe... and on reaches of unimaginable horror. When prospector Bob Broadhead went out to Gateway on the Heechee spacecraft, he decided he would know which was the right mission to make him his fortune. Three missions later, now famous and permanently rich, Robinette Broadhead has to face what happened to him and what he is... in a journey into himself as perilous and even more horrifying than the nightmare trip through the interstellar void that he drove himself to take!

Critics have compared the engrossing space operas of Peter F. Hamilton to the classic sagas of such sf giants as Isaac Asimov and Frank Herbert. But Hamilton's bestselling fiction--powered by a fearless imagination and world-class storytelling skills--has also earned him comparison to Tolstoy and Dickens. Hugely ambitious, wildly entertaining, philosophically stimulating: the novels of Peter F. Hamilton will change the way you think about science fiction. Now, with Pandora's Star, he begins a new multivolume adventure, one that promises to be his most mind-blowing yet.

The year is 2380. The Intersolar Commonwealth, a sphere of stars some four hundred light-years in diameter, contains more than six hundred worlds, interconnected by a web of transport "tunnels" known as wormholes. At the farthest edge of the Commonwealth, astronomer Dudley Bose observes the impossible: Over one thousand light-years away, a star... vanishes. It does not go supernova. It does not collapse into a black hole. It simply disappears. Since the location is too distant to reach by wormhole, a faster-than-light starship, the Second Chance, is dispatched to learn what has occurred and whether it represents a threat. In command is Wilson Kime, a five-time rejuvenated ex-NASA pilot whose glory days are centuries behind him.

Opposed to the mission are the Guardians of Selfhood, a cult that believes the human race is being manipulated by an alien entity they call the Starflyer. Bradley Johansson, leader of the Guardians, warns of sabotage, fearing the Starflyer means to use the starship's mission for its own ends,.

Pursued by a Commonwealth special agent convinced the Guardians are crazy but dangerous, Johansson flees. But the danger is not averted. Aboard the Second Chance, Kime wonders if his crew has been infiltrated. Soon enough, he will have other worries. A thousand light-years away, something truly incredible is waiting: a deadly discovery whose unleashing will threaten to destroy the Commonwealth... and humanity itself.

Could it be that Johansson was right?

Peter F. Hamilton's superbly imagined, cunningly plotted interstellar adventures are conceived on a staggeringly epic scale and filled with fully realized human and alien characters as complex as they are engaging. No mere world builder, Hamilton creates entire universes–and he does so with irresistible flair and intelligence. His previous novel, the acclaimed Pandora's Star, introduced the Intersolar Commonwealth, a star-spanning civilization of the twenty-fourth century. Robust, peaceful, and confident, the Commonwealth dispatched a ship to investigate the mystery of a disappearing star, only to inadvertently unleash a predatory alien species that turned on its liberators, striking hard, fast, and utterly without mercy.

The Prime are the Commonwealth's worst nightmare. Coexistence is impossible with the technologically advanced aliens, who are genetically hardwired to exterminate all other forms of life. Twenty-three planets have already fallen to the invaders, with casualties in the hundreds of millions. And no one knows when or where the genocidal Prime will strike next.

Nor are the Prime the only threat. For more than a hundred years, a shadowy cult, the Guardians of Selfhood, has warned that an alien with mind-control abilities impossible to detect or resist–the Starflyer–has secretly infiltrated the Commonwealth. Branded as terrorists, the Guardians and their leader, Bradley Johansson, have been hunted by relentless investigator Paula Myo. But now evidence suggests that the Guardians were right all along, and that the Starflyer has placed agents in vital posts throughout the Commonwealth–agents who are now sabotaging the war effort. Is the Starflyer an ally of the Prime, or has it orchestrated a fight to the death between the two species for its own advantage?

Caught between two deadly enemies, one a brutal invader striking from without, the other a remorseless cancer killing from within, the fractious Commonwealth must unite as never before.

This will be humanity's finest hour–or its last gasp.

In a moving story of sacrifice and triumph, human scientists establish a relationship with intelligent lifeforms--the cheela--living on Dragon's Egg, a neutron star where one Earth hour is equivalent to hundreds of their years. The cheela culturally evolve from savagery to the discovery of science, and for a brief time, men are their diligent teachers . . .

Who's testing whom? When Kris Kelvin arrives at the planet Solaris to study the ocean that covers its surface, he is forced to confront a painful, hitherto unconscious memory embodied in the living physical likeness of a long-dead lover. Others examining the planet, Kelvin learns, are plagued with their own repressed and newly corporeal memories. Scientists speculate that the Solaris ocean may be a massive brain that creates these incarnate memories, its purpose in doing so unknown.

The first of Lem's novels to be published in America and now considered a classic, SOLARIS raises a question: Can we truly understand the universe around us without first understanding what lies within?

Lem himself, who read English fluently, repeatedly voiced his disappointment about the Kilmartin-Cox translation of the French translation, and it has generally been considered second-rate. In 2011, the first direct Polish-to-English translation by Bill Johnston was released as an audiobook narrated by Alessandro Juliani, and then as an e-book.

The planet Quinta is pocked by ugly mounds and covered by a spiderweb-like network. It is a kingdom of phantoms and of a beauty afflicted by madness. In stark contrast, the crew of the spaceship Hermes represents a knowledge-seeking Earth. As they approach Quinta, a dark poetry takes over and leads them into a nightmare of misunderstanding.

Earth is reeling from the revelation of a coming alien invasion—in just four centuries' time. The aliens' human collaborators may have been defeated, but the presence of the sophons, the subatomic particles that allow Trisolaris instant access to all human information, means that Earth's defense plans are totally exposed to the enemy. Only the human mind remains a secret. This is the motivation for the Wallfacer Project, a daring plan that grants four men enormous resources to design secret strategies, hidden through deceit and misdirection from Earth and Trisolaris alike. Three of the Wallfacers are influential statesmen and scientists, but the fourth is a total unknown. Luo Ji, an unambitious Chinese astronomer and sociologist, is baffled by his new status. All he knows is that he's the one Wallfacer that Trisolaris wants dead.

Half a century after the Doomsday Battle, the uneasy balance of Dark Forest Deterrence keeps the Trisolaran invaders at bay. Earth enjoys unprecedented prosperity due to the infusion of Trisolaran knowledge. With human science advancing daily and the Trisolarans adopting Earth culture, it seems that the two civilizations will soon be able to co-exist peacefully as equals without the terrible threat of mutually assured annihilation. But the peace has also made humanity complacent.

Cheng Xin, an aerospace engineer from the early 21st century, awakens from hibernation in this new age. She brings with her knowledge of a long-forgotten program dating from the beginning of the Trisolar Crisis, and her very presence may upset the delicate balance between two worlds. Will humanity reach for the stars or die in its cradle?

One of Niven's most beloved characters, Beowulf Shaeffer, is forced to take a dangerous mission to explore a neutron star. The last group who went there never came back alive, but Shaeffer faces life imprisonment if he doesn't take the job. Will he determine the mysterious force that turned the prior crew to hamburger before he suffers a similar fate?

Hugo Award winner "Neutron Star" and seven other groundbreaking stories and novellas by the author of RINGWORLD.

In the year 3016, the Second Empire of Man spans hundreds of star systems, thanks to the faster-than-light Alderson Drive. No other intelligent beings have ever been encountered, not until a light sail probe enters a human system carrying a dead alien. The probe is traced to the Mote, an isolated star in a thick dust cloud, and an expedition is dispatched.

In the Mote the humans find an ancient civilization--at least one million years old--that has always been bottled up in their cloistered solar system for lack of a star drive. The Moties are welcoming and kind, yet rather evasive about certain aspects of their society. It seems the Moties have a dark problem, one they've been unable to solve in over a million years.

David Brin's Uplift novels are among the most thrilling and extraordinary science fiction ever written. Sundiver, Startide Rising, and The Uplift War -- a New York Times bestseller -- together make up one of the most beloved sagas of all time. Brin's tales are set in a future universe in which no species can reach sentience without being "uplifted" by a patron race. But the greatest mystery of all remains unsolved: who uplifted humankind?

The Terran exploration vessel Streaker has crashed in the uncharted water world of Kithrup, bearing one of the most important discoveries in galactic history. Below, a handful of her human and dolphin crew battles armed rebellion and a hostile planet to safeguard her secret -- the fate of the Progenitors, the fabled First Race who seeded wisdom throughout the stars.

The Age of Death ended countless millennia ago. No longer burdened by limited lifespans, the immortal humans who populate inhabited space now have the luxury to travel vast distances effortlessly and to tinker with the intricate mechanics of spacetime. But one such experiment in quantum physics has had a catastrophic and unanticipated result, creating an enormous, rapidly expanding vacuum -- a region of new physics -- with the frightening potential to devour countless inhabited solar systems.

Tchicaya abandoned his homeworld four thousand years ago to travel the universe, freely choosing, as have others of his bent, to endure the hardships of distance and loneliness for the sake of knowledge and experience. Aboard the Rindler, a starship trawling the border of the allconsuming novo-vacuum, he feels his endless life has new purpose. For the Rindler is the center for the scientific study the phenomenon -- a common ground for Preservationists and Yielders alike, those working to halt and destroy the encroaching worlds-eater ... and those determinedto investigate its marvels while allowing its growth to continue unchecked. Tchicaya has allied himself firmly with the latter camp.

The passing decades -- and inevitable expansion of the void -- widen the great rift between the two factions, intensifying what was once simply ideological differences into something more angry, explosive, and dangerous. And the arrival of Tchicaya's fiery first love, Mariama, and her immediate embracing of the Preservationist cause, intensifies an inner turmoil he has been struggling with since his distant childhood.

But everything onboard the Rindler -- and, ultimately, in the inhabited universe itself-is on the cusp of further cataclysmic change, as the Yielders' explorations threaten to transform discord into violent action and potential xenocide. For new evidence suggests that something unthinkable is developing at an astounding rate deep within the mysterious, 600-light-years-wide void -- something neither Tchicaya and his compatriots nor Mariama and hers could ever have imagined possible: life.

Dr. Dan Sylveste, an archaeologist who has for years been fascinated with the long-dead alien race the Amarantin, is about to discover something that could change the course of mankind. But before he can act on anything his wife is killed and he is captured when a coup sweeps across the planet Resurgam. Meanwhile, an astonishing ship bearing a crew of militaristic cyborgs and a kidnapped Gunnery Officer is bearing down on Resurgam, crossing light years of space to enlist Sylveste's help to save their metamorphosing Captain. Only Sylveste, or, more accurately, the software programme containing his father's knowledge that he carries in his mind, can save the Captain. None of them can anticipate the cataclysm that will result when they meet, a cataclysm that will sweep through space and could determine the ultimate fate of humanity.

Some centuries from now, the exploration and exploitation of the Solar System is in full swing. On the cold edge of the system, Bella Lind, captain of the huge commercial spacecraft Rockhopper IV, helps fuel this new gold rush by attaching mass-driver motors to organic-rich water-ice comets to move them back to the inner worlds. Her crew are tough, blue-collar miners, engineers and demolition experts. Around Saturn, something inexplicable happens: one of the moons leaves its orbit and accelerates out of the Solar System. The icy mantle peels away to reveal that it was never a moon in the first place, just a parked spacecraft, millions of years old, that has now decided to move on. Rockhopper IV, trapped in the pull, is hurled across time and space into the deep, distant future, arriving in a vast, alien-constructed chamber. And the crew are not alone, for each chamber contains an alien culture dragged into this cosmic menagerie at the end of time. The crew of the Rockhopper IV know a lot about blowing up comets, but not much about first contact with ultra-advanced aliens.

They have two things to worry about: can they (and their new alien allies) negotiate their way through each harrying contact? And can they assimilate the avalanche of knowledge about their own future - including all the glittering, dangerous technologies that are now theirs for the taking - without destroying themselves in the process?

AURORA tells the incredible story of our first voyage beyond the solar system.

Our voyage from Earth began generations ago.

Now, we approach our destination.

A new home.

AURORA.

Grant Archer only wanted to study astrophysics. But the forces of the "New Morality," the coalition of censorious do-gooders who run 21st-century America, have other plans for him.

To his distress, Grant is torn from his young bride and sent to a research station in orbit around Jupiter, to spy on the scientists who work there. Their work may lead to the discovery of higher life forms in the Jovian system-with implications the New Morality doesn't like at all.

What Grant's would-be controllers don't know is that his loyalty to science may be greater than his desire for a quiet life. But that loyalty will be tested in a mission as dangerous as any ever undertaken-a mission to the middle reaches of Jupiter's endless atmosphere, a place where hydrogen flows as a liquid, and cyclones larger than planets rage for centuries at a time.

What lurks there is more than anyone has counted on...and stranger than anyone could possibly have imagined.

A spellbinding epic adventure of discovery, catastrophe, and survival from one of the most masterful storytellers in speculative fiction.

In the year 2204, tragedy and terror forced a scientific team to prematurely evacuate Maleiva III. Twenty-one years later, the opportunity for scientists to study this galactic rarity -- a life-supporting planet -- is about to vanish forever, as a rogue gas giant has invaded the planetary system on a deadly collision course with the world they are now calling Deepsix.

A superluminal pilot for the Academy of Science and Technology, Priscilla "Hutch" Hutchins is the only even remotely qualified professional within lightyears of Deepsix. With less than three weeks left before the disaster, she and a small scientific team -- including Randall Nightingale, a survivor of the original expedition who was made the scapegoat for its failure -- must descend to the surface, and glean whatever they can about the doomed planet's lifeforms and lost civilizations.

There is more to this strange and complex world, however, than anyone could have imagined: hidden predators stone cities under the ice remnants of a warlike, primitive society, yet with inexplicable hints of an impossible technology buried in the rubble ... and in orbit around the soon to be demolished planet. The deeper Hutch and her team delve, the more puzzles are revealed within puzzles, and startling discoveries lead only to greater and more perplexing questions.

But then the unthinkable occurs. An earthquake destroys the explorers' only means of escape. As scientists and sightseers who have come to witness the spectacular end of Deepsix watch helplessly from miles above, Hutch and her people must survive somehow on a hostile planet going rapidly mad. And with the clock ticking relentlessly toward an unavoidable apocalypse, they must find some way, any way, to get off before Deepsix plunges like a pebble into the limitless depths of the rampaging gas giant.

From the acclaimed author of Infinity Beach comes the ultimate survival adventure -- a riveting, relentlessly suspenseful, awesomely possible tale with a firm foundation in hard science which showcases the best and the worst aspects of complex human nature. It is yet another stunning achievement by Jack McDevitt, proving without a doubt that he is indeed the true heir to Isaac Asimov and Arthur C. Clarke.

Coyote marks a dramatic new turn in the career of Allen Steele, Hugo Award-winning author of Chronospace. Epic in scope, passionate in its conviction, and set against a backdrop of plausible events, it tells the brilliant story of Earth's first interstellar colonists-and the mysterious planet that becomes their home.

The crime of the century begins without a hitch. On July 5th, 2070, as it's about to be launched, the starship Alabama is hijacked-by her captain and crew. In defiance of the repressive government of The United Republic of Earth, they replace her handpicked passengers with political dissidents and their families. These become Earth's first pioneers in the exploration of space. Captain R.E. Lee, their leader. Colonel Gill Reese, the soldier sent to stop Lee. Les Gilles, the senior communications officer, a victim of a mistake that will threaten the entire mission. Crewman Eric Gunther, who has his own agenda for being aboard. His daughter, Wendy, a teenager who will grow up too quickly.

Jorge and Rita Montero, ordinary people caught up in extraordinary circumstances. And their son Carlos, who will become a hero in spite of himself. After almost two-and-a-half centuries in cold sleep, they will awaken above their destination: a habitable world named Coyote. A planet that will test their strength, their beliefs, and their very humanity. In Coyote, Allen Steele delivers a grand novel of galactic adventure-a tale of life on the newest of frontiers.

Golden Age SF meets Golden Age Crime from the author of Swiftly, New Model Army, and Yellow Blue Tibia-an innovative literary voice working at the height of his powers

Jack Glass is the murderer-we know this from the start. Yet as this extraordinary novel tells the story of three murders committed by Glass, the reader will be surprised to find out that it was Glass who was the killer and how he did it. And by the end of the book our sympathies for the killer are fully engaged. Riffing on the tropes of crime fiction (the country house murder, the locked room mystery) and imbued with the feel of golden age SF, this is another bravura performance from Roberts. Whatever games he plays with the genre, whatever questions he asks of the reader, Roberts never loses sight of the need to entertain.

This novel has some wonderfully gruesome moments, is built around three gripping HowDunnits, and comes with liberal doses of sly humor. Roberts invites us to have fun and tricks us into thinking about both crime and SF via a beautifully structured novel set in a society whose depiction challenges notions of crime, punishment, power, and freedom.

In Book Two of the Heechee Saga, Robinette Broadhead is on his way to making a fortune by bankrolling an expedition to the Food Factory--a Heechee spaceship that can graze the cometary cloud and transfor the basic elements of the universe into untold quantities of food. But even as he gambles on the breakthrough technology, he is wracked with the guilt of losing his wife, poised forever at the "event horizon" of a black hole where Robin had abaondoned her. As more and more information comes back from the expedition, Robin grows ever hopeful that he can rescue his beloved Gelle-Klara Moynlin. After three and a years, the factory is discovered to work, and a human is found aboard. Robin's suffering may be just about over....

First there were good times: humankind reached glorious heights, even immortality. Then there were bad times: Earth was occupied by the faceless, brutal Qax. Immortality drugs were confiscated, the human spirit crushed. Earth became a vast factory for alien foodstuffs.

Into this new dark age appears the end of a tunnel through time. Made from exotic matter, it is humanity's greatest engineering project in the pre-Qax era, where the other end of the tunnel remains anchored near Jupiter. When a small group of humans in a makeshift craft outwit the Qax to escape to the past through the tunnel, it is not to warn the people of Earth against the Qax, who are sure to follow them. For these men and women from the future are themselves dangerous fanatics in pursuit of their own bizarre quantum grail.

Michael Poole, architect of the tunnel, must boldly confront the consequences of his genius.

Timelike Infinity: the strange region at the end of time where the Xeelee, owners of the universe, are waiting...

The surface of Venus is the most hellish place in the solar system. The ground is hot enough to melt aluminum. The air pressure is so high it has crushed spacecraft landers as though they were tin cans. The sky is perpetually covered with clouds of sulfuric acid. The atmosphere is a choking mixture of carbon dioxide and poisonous gases.

This is where Van Humphries must go. Or die trying.

His older brother perished in the first attempt to land a man on Venus, years before, and his father had always hated Van for surviving when his brother died. Now his father is offering a ten billion dollar prize to the first person to land on Venus and return his oldest son's remains.

To everyone's surprise, Van takes up the offer. But what Van Humphries will find on Venus will change everything--our understanding of Venus, of global warming on Earth, and his knowledge of who he is.

Set against the backdrop of China's Cultural Revolution, a secret military project sends signals into space to establish contact with aliens. An alien civilization on the brink of destruction captures the signal and plans to invade Earth. Meanwhile, on Earth, different camps start forming, planning to either welcome the superior beings and help them take over a world seen as corrupt, or to fight against the invasion.

While the human race struggles against alien oppressors, an even greater epic battle rages between the deadly dark-matter photino birds and their implacable enemy, the Xeelee...

Moving Mars is a story of human courage and love set within the greater saga of a planetary liberation movement. Mars is a colonial world, governed by corporate interests on Earth. The citizens of Mars are hardworking, but held back by their lack of access to the best education, and the desire of the Earthly powers to keep the best new inventions for themselves. The young Martians -- the second and third generations born on Mars -- have little loyalty to Earth, and a strong belief that their planet can be independent. The revolution begins slowly, but will grow in power over decades of political struggle until it becomes irresistible.

Told through the eyes of an extraordinary character, Casseia Majumdar, a daughter of one of Mars' oldest, most conservative Binding Multiples, Moving Mars is Greg Bear's brilliant conception of the human colonization of the red planet, with lovingly painted details and a grand historical sweep, embellishing an audacious scientific speculation.

Captain John "Black Jack" Geary tries a desperate gamble to lead the Alliance Fleet home-through enemy-occupied space-only to lose half the Fleet to an unexpected mutiny.

Thousands of years after an entire colony mysteriously disappears, antiquities dealer Alex Benedict comes into possession of a cup that seems to be from the Seeker, one of the colony's ships. Investigating the provenance of the cup, Alex and his assistant Chase follow a deadly trail to the Seeker-strangely adrift in a system barren of habitable worlds. But their discovery raises more questions than it answers, drawing Alex and Chase into the very heart of danger.

Phssthpok the Pak had been traveling for most of his thirty-two thousand years. His mission: save, develop, and protect the group of Pak breeders sent out into space some two and a half million years before...

Brennan was a Belter, the product of a fiercely independent, somewhat anarchic society living in, on, and around an outer asteroid belt. The Belters were rebels, one and all, and Brennan was a smuggler. The Belt worlds had been tracking the Pak ship for days -- Brennan figured to meet that ship first...

He was never seen again -- at least not by those alive at the time.

Pierson's puppeteers, strange, three-legged, two-headed aliens, have discovered an immense structure in a hitherto unexplored part of the universe. Frightened of meeting the builders of such a structure, the puppeteers set about assembling a team consisting of two humans, a puppeteer and a kzin, an alien not unlike an eight-foot-tall, red-furred cat, to explore it. The artefact is a vast circular ribbon of matter, some 180 million miles across, with a sun at its centre - the Ringworld. But the expedition goes disastrously wrong when the ship crashlands and its motley crew faces a trek across thousands of miles of the Ringworld's surface.

Thalassa was a paradise above the earth. Its beauty and vast resources seduce its inhabitants into a feeling of perfection. But then the Magellan arrives, carrying with it one million refugees from the last mad days of earth. Paradise looks indeed lost....

An odyssey of discovery, from a shattered society through the solar system with a handful of men and women who ride a cold, hurtling ball of ice to the shaky promise of a distant, unknowable future.

A civilization-destroying omega cloud has switched direction, heading straight for a previously unexplored planetary system -- and its alien society. And suddenly, a handful of brave humans must try to save an entire world -- without revealing their existence.

To boost waning interest in interstellar travel, a mission is sent into deep space to learn the truth about "moonriders," the strange lights supposedly being seen in nearby systems. But the team soon discovers that their odyssey is no mere public-relations ploy, for the moonriders are not a harmless phenomenon. They are very, very dangerous-in a way that no one could possibly have imagined.

The Forge of God described the destruction of Earth itself by self-replicating robots, Von Neumann machines designed to use the planet's mass to create more robotic creatures and spread throughout the Galaxy. Only a few humans have survived, aided by a mysterious alien race known only as “The Benefactors”, who arrived at Earth too late.

Now the small group of human survivors is determined to track down the criminal race who launched the planet killers. Humanity is given a starship by The Benefactors, and driven only by revenge they set out to find the unknown beings who are responsible for the destruction of Earth, and many other worlds.

STEP INTO THE FOLD.

IT'S PERFECTLY SAFE.

The folks in Mike Erikson's small new England town would say he was just your average, everyday guy. And that's exactly how Mike likes it. Sure, the life he's chosen isn't much of a challenge to someone with his unique gifts, but he's content with his quiet and peaceful existence.

That is, until an old friend presents him with an irresistable mystery, one that Mike is uniquely qualified to solve: far out in the California desert, a team of DARPA scientist has invented a device they affectionately call the Albuquerque Door. Using a cryptic computer equation and magnetic fields to "fold" dimensions, it shrinks distances so a traveler can travel hundreds of feet in a single step.

The invention promises to make mankind's dreams of teleportation a reality. And, the scientists insist, travelling through the Door is completely safe.

Yet evidence is mounting that this miraculous machine isn't quite what it seems -- and that its creators are harboring a dangerous secret.

As his investigation draws him deeper into the puzzle, Mike begins to fear there is only one answer that makes sense, And if he's right, it may be only a matter of time before the project destroys... everything.

The Beyond started with the Stations orbiting the stars nearest Earth. The Great Circle the interstellar freighters traveled was long, but not unmanageable, and the early Stations were emotionally and politically dependent on Mother Earth. The Earth Company which ran this immense operation reaped incalculable profits and influenced the affairs of nations.

Then came Pell, the first station centered around a newly discovered living planet. The discovery of Pell's World forever altered the power balance of the Beyond. Earth was no longer the anchor which kept this vast empire from coming adrift, the one living mote in a sterile universe.

But Pell was just the first living planet. Then came Cyteen, and later others, and a new and frighteningly different society grew in the farther reaches of space. The importance of Earth faded and the Company reaped ever smaller profits as the economic focus of space turned outward. But the powerful Earth Fleet was sitll a presence in the Beyond, and Pell Station was to become the last stronghold in a titanic struggle between the vast, dynamic forces of the rebel Union and those who defended Earth's last, desperate grasp for the stars.

Fifty men and women set out in the twenty-third century from Earth aboard an interstellar craft to travel to a planet some thirty light-years away. The ship will approach the speed of light and so (as Einstein predicted) subjective time on board will slow and so the journey of several decades will be of much shorter duration for the crew. But the ship's deceleration system is irreparably damaged when it hits a cloud of interstellar dust and acceleration continues toward light speed, tau zero. Soon the ship is speeding through galaxies and eons are passing on board the ship in the blink of an eye ...

The passengers on the spaceship Argo, pursued by hostile ""mechs,"" must face their doubts about their captain's obsession with finding the galaxy's True Center, an obsession that even troubles the captain's son.

Jamie Waterman is a young Navaho geologist who is picked for the ground team of the first manned expedition to Mars. He will be joining an international team of astronauts and scientists. But once the crew land on the red planet, they soon discover they must battle not only the alien land on which they have invaded but earthbound bureaucrats as well. When they come face to face with a chasm ten times as deep and large as the Grand Canyon, all twenty-five astronauts must face the most shocking discovery of all...

We are alone. That is the verdict, after centuries of Search for Extra-Terrestrial Intelligence missions and space exploration. The only living things in the Universe are found on the Nine Worlds settled from Earth, and the starships that knit them together. Or so it's believed, until Dr. Kimberly Brandywine sets out to find what happened to her clone-sister Emily, who, after the final, unsuccessful manned SETI expedition, disappeared along with the rest of her ship's crew.

Following a few ominous clues, Kim discovers the ship's log was faked. Something happened out there in the darkness between the stars, and she's prepared to go to any length to find answers. Even if it means giving up her career...stealing a starship...losing her lover. Kim is about to discover the truth about her sister -- and about more than she ever dared imagine.

Many years ago humans made a discovery in the far reaches of the solar system - a huge statue of an alien creature, with a description that defied all efforts of translation. But except for a set of footprints on Jupiter's moon, there is no trace of the race that has left it behind.

Life might emerge under the most unlikely conditions... or in the last extremity.

A century into the future, technology has solved most of the problems that have plagued our time. However, a new problem is on the horizon-one greater than humanity has ever faced. A massive asteroid is racing toward the earth, and its impact could destroy all life on the planet.

Immediately after the asteroid-named "Kali" after the Hindu goddess of chaos and destruction-is discovered, the world's greatest scientists begin their search for a way to prevent disaster. In the meantime, Captain Robert Singh, aboard the starship Goliath, may be the only person who can stop the asteroid. But this heroic role may demand the ultimate sacrifice.

H. G. Wells' 1901 science fiction novel, "The First Men in the Moon", is the story of an impoverished businessman, Mr. Bedford, who retreats to the countryside for some rest from the weary of modern life and to try his hand at authoring a play. While there he meets an eccentric scientist, Dr. Cavor, who is developing a new material, 'cavorite', which is designed to shield off gravity. When it is discovered that the material works and can be practically fashioned into a spaceship, the two undertake a mission to the moon. There they discover that the moon is inhabited by a sinister alien civilization, whom the call "the Selenites".

Fashioned as a criticism against imperialism, "The First Men in the Moon" draws upon a theme common to Wells' work, that of the impact of technology on society and the challenges that humans face in the modern world.

The planet was called Pyrrus...a strange place where all the beasts, plants and natural elements were designed for one specific purpose: to destroy man.

The settlers there were supermen...twice as strong as ordinary men and with milli-second reflexes. They had to be. For their business was murder...

It was up to Jason dinAlt, interplanetary gambler, to discover why Pyrrus had become so hostile during man's brief habitation...

Ender’s Shadow explores the stars in this all-new novel...

At the end of Shadow of the Giant, Bean flees to the stars with three of his children--the three who share the engineered genes that gave him both hyper-intelligence and a short, cruel physical life. The time dilation granted by the speed of their travel gives Earth’s scientists generations to seek a cure, to no avail. In time, they are forgotten--a fading ansible signal speaking of events lost to Earth’s history. But the Delphikis are about to make a discovery that will let them save themselves, and perhaps all of humanity in days to come.

For there in space before them lies a derelict Formic colony ship. Aboard it, they will find both death and wonders--the life support that is failing on their own ship, room to grow, and labs in which to explore their own genetic anomaly and the mysterious disease that killed the ship’s colony.

After millennia had passed, Mankind discovered the Heechee legacy (an alien culture that fled to the reative safety of a black hole) -- in particular an asteroid stocked with autonavigating spacecraft. Robinette Broadhead, who had led the expedition that unlocked the many secrets of Heechee technology, is now forced once more to make a perilous voyage into space -- where the Heechee are waiting. And this time the future of Man is at stake....

Robert Heinlein called it "possibly the finest science fiction novel I have ever read." The San Francisco Chronicle declared that "as science fiction, The Mote in God's Eye is one of the most important novels ever published." Now Larry Niven and Jerry Pournelle, award winning authors of such bestsellers as Footfall and The Legacy of Heorot, return us to the Mote, and to the universe of Kevin Renner and Horace Bury, of Rod Blaine and Sally Fowler.

There, 25 years have passed since humanity quarantined the mysterious aliens known as Moties within the confines of their own solar system. They have spent a quarter century analyzing and agonizing over the deadly threat posed by the only aliens mankind has ever encountered-- a race divided into distinct biological forms, each serving a different function. Master, Mediator, Engineer. Warrior. Each supremely adapted to its task, yet doomed by millions of years of evolution to an inescapable fate. For the Moties must breed-- or die. And now the fragile wall separating them and the galaxy beyond is beginning to crumble.

Six years after the first manned Martian expedition, a second has been announced -- one motivated purely by its profitable potential -- and half-Navajo, half-Anglo geologist Jamie Waterman's conflicted soul is beckoning him back to the eerie, unforgiving planet.

As commander of the new exploratory team, he will have to contend with a bitter and destructive rivalry, a disturbing new emotional attraction, and deadly, incomprehensible "accidents" that appear to be sabotage, all of which could doom the mission to failure.

But there is much more at stake than Waterman's personal redemption and the safety of his crew. For there are still great secrets to be uncovered on this cruel and enigmatic world -- not the least being something he glimpsed in the far distance during his first Martian excursion: an improbable structure perched high in the planet's carmine cliffs; a dwelling that only an intelligent being could have built.

Paula Benacerraf is appointed to oversee the dismantling of the Shuttle fleet after another disaster. Instead, she listens to the scientist, Rosenberg, who wants to explore the life Cassini discovers on Titan. Humans are hurled to the edge of the Solar System. To the edge, also, of sanity.

The year is 2010. More than a century of ecological damage, industrial and technological expansion, and unchecked population growth has left the Earth on the brink of devastation. But as the world's governments turn inward, one man dares to gamble on a bolder, brighter future. That man--Reid Malenfant--has a very different solution to the problems plaguing the planet: the exploration and colonization of space.

Battling national sabotage and international outcry, Malenfant's bootstrap company builds a spacecraft, plots its course, and trains the genetically enhanced Sheena 5 for her one-way journey. As apocalyptic riots sweep the globe, Malenfant launches the rocket. But Sheena has plans of her own. And even as she sets them in motion, the situation on Earth grows more desperate and violent.

Now Malenfant--together with a brilliant but disturbed mathematician, a child prodigy, and his ex-wife--must gamble the very existence of time and space on a single desperate throw of the dice. The odds are a trillion to one against him...

Or are they?

The mining ship El Cavador is far out from Earth, in the deeps of the Kuiper Belt, beyond Pluto. Other mining ships, and the families that live on them, are few and far between this far out. So when El Cavador's telescopes pick up a fast-moving object coming in-system, it's hard to know what to make of it. It's massive and moving at a significant fraction of the speed of light.

El Cavador has other problems. Their systems are old and failing. The family is getting too big for the ship. There are claim-jumping corporate ships bringing Asteroid Belt tactics to the Kuiper Belt. Worrying about a distant object that might or might not be an alien ship seems...not important.

They're wrong. It's the most important thing that has happened to the human race in a million years. The first Formic War is about to begin.

Time is running out for the passengers and crew of the tourist-cruiser "Selene", incarcerated in a sea of choking lunar dust. On the surface, her rescuers find their resources stretched to the limit by the pitiless and unpredictable conditions of a totally alien environment.

Visionary space industrialist Dan Randolph is dead-but his protégé, pilot Pancho Barnes, now sits on the board of his conglomerate. She has her work cut out for her. For Randolph's rival Martin Humphries still wants to control Astro and still wants to drive independent asteroid miners like Lars Fuchs out of business. Humphries wants revenge against Pancho-ands, most of all, he wants his old flame Amanda, who has become Lars Fuchs's wife.

In the struggle over the incalculable wealth of the Asteroid Belt, many will die-and many will achieve more than they ever dreamed was possible.

Merchanter Cargo Chief Marie Hawkins has never forgiven the crime, nor sought justice. Only vengeance. And, for 23 years, the Hawkins's clan ship, Sprite, has lived with her vendetta – and with her son, Tom, the boy sired in the violent assault.

Marie's attacker, Austin Bowe, is captain of the Corinthian. When both ships dock at Mariner Station, Marie vanishes and Tom searches for his mother... only to find himself trapped on Austin's ship with a half-brother he never knew he had and a crew fanatically loyal to Bowe. Now as the Corinthian flees the pursuing Sprite and a raider guns after both, the lives on board the two Merchanter ships are in the hands of Tom Hawkins. To save them all, Tom must trust his sworn enemy...

His father.

SKYJACKED!

One minute Kip Russell is walking around his own backyard, testing out an old space suit and dreaming about going to the moon - the next he is the captive of a space pirate and on his way to the very place he had been dreaming of. At first, the events are so unreal he thinks he might be having a nightmare... but when he discovers other prisoners aboard the spaceship he knows the ordeal is all too real. Kip and his fellow abductees, the daughter of a world-renowned scientist and a beautiful creature from an alien planet, have been skyjacked by a monstrous extraterrestrial who is flying them to the moon on a journey toward a fate worse than death....

Ben Bova's extraordinary Moonbase Saga continues with a breathtaking near-future adventure rich in character and incident. The action begins seven years after the indomitable Stavenger family has realized its cherished dream of establishing a colony on the inhospitable lunar surface.

Moonbase is now a thriving community under the leadership of Doug Stavenger, a marvel of scientific ahievement created and supported by nanotechnology: virus-size machines that can build, cure, and destroy. But nanotechnology has been declared illegal by the home planet's leaders. And a powerful despot is determined to lay claim to Stavenger's peaceful city... or obliterate it, if necessary. The people of Moonbase--a colony with no arms or military--must now defend themselves from earth-born aggression with the only weapon at their disposal: the astonishing technology that sustains their endangered home.

The story of The First Formic War continues in Earth Awakens.

Nearly 100 years before the events of Orson Scott Card's bestselling novel Ender's Game, humans were just beginning to step off Earth and out into the Solar System. A thin web of ships in both asteroid belts; a few stations; a corporate settlement on Luna. No one had seen any sign of other space-faring races; everyone expected that First Contact, if it came, would happen in the future, in the empty reaches between the stars. Then a young navigator on a distant mining ship saw something moving too fast, heading directly for our sun.

When the alien ship screamed through the solar system, it disrupted communications between the far-flung human mining ships and supply stations, and between them and Earth. So Earth and Luna were unaware that they had been invaded until the ship pulled into Earth orbit, and began landing terra-forming crews in China. Politics and pride slowed the response on Earth, and on Luna, corporate power struggles seemed more urgent than distant deaths. But there are a few men and women who see that if Earth doesn't wake up and pull together, the planet could be lost.

Here is the compelling story of the launching of Prometheus -- Earth's first true spaceship -- and of the men who made it happen.

Dirk Alexson:
Chronicler of the greatest space adventure of all time, he was chosen to immortalize the incredible story of the men and their heroic mission.

Sir Robert Derwent:
Direct-General of Interplanetary -- London Headquarters for the international space-flight project -- he was the man who got the mission off the ground and into the pages of history.

Professor Maxton:
The world's leading atomic engineer, he designed the huge ship's drive units and he waited with the rest of the world to see if the project would be a success.

This debut novel from preeminent science-fiction writer Ursula LeGuin introduces her brilliant Hainish series, set in a galaxy seeded by the planet Hain with a variety of humanoid species, including that of Earth. Over the centuries, the Hainish colonies have evolved into physically and culturally unique peoples, joined by a League of All Worlds.

Earth-scientist Rocannon has been leading an ethnological survey on a remote world populated by three native races: the cavern-dwelling Gdemiar, the elvish Fiia, and the warrior clan, Liuar. But when the technologically primitive planet is suddenly invaded by a fleet of ships from the stars, rebels against the League of All Worlds, Rocannon is the only survey member left alive. Marooned among alien peoples, he leads the battle to free this newly discovered world and finds that legends grow around him as he fights.

The Way is a tunnel through space and time. The entrance is through the hollow asteroid Thistledown and the space station Axis City that sits at the asteroid's center. From there the Flawships ride the center of the Way, traveling to other worlds and times.

Now the rulers of Axis City have discovered that a huge group of colonists has secretly entered one of the interdicted worlds along the Way. In some ways Lamarkia is very Earth-like--but its biology is extraordinary. A single genetic entity can take many forms, and span a continent. There are only a few of these "ecos" on Lamarkia, and the effect of human interaction on them is unknown.

Olmy Ap Sennon has been sent to secretly assess the extent of the damage. But he will find far more than an intriguing alien biology--for on their new world the secret colonists have returned to the old ways of human history: war, famine, and ecological disaster. On this mission, Olmy will learn about the basics: love, responsibility, and even failure...

Dorothy Yoshida, an astronomer and telepath, joins the archaelogical team exploring the mysterious ruins of a nearly dead planet that shows some signs of returning to life.

Years ago, the enormous, enigmatic alien spacecraft called Rama sailed through our solar system as mind-boggling proof that life existed -- or had existed -- elsewhere in the universe. Now, at the dawn of the twenty-third century, another ship is discovered hurtling toward us. A crew of Earth's best and brightest minds is assembled to rendezvous with the massive vessel. They are armed with everything we know about Raman technology and culture. But nothing can prepare them for what they are about to encounter on board Rama II: cosmic secrets that are startling, sensational -- and perhaps even deadly.

After the effortless capture of Earth by vastly superior aliens, humanity is forced to fight for existence on the Moon and other lumps of airless rock. The invention of the Hotline -- a constant stream of data from a star in the constellation Ophiuchus -- facilitates survival and enables the development of amazing new technologies.

Then, after 400 years, humanity's unknown helpers send a bill for their services... and suddenly everything is threatened once again.

The Ophiuchi Hotline was John Varley's first novel, and it received nominations for both the Hugo and Nebula awards he later won both for his book Persistence of Vision.

Aboard Null Boundary, a giant starship thousands of years old, four survivors of an ancient alien war are making a desperate journey: Lot, son of a fiery prophet and carrier of an insidious virus that spreads a cultlike religious mania among those it infects; Urban, Lot's boyhood friend from the city of Silk, and a man in search of challenge and adventure; Clemantine, cast adrift when her world was destroyed, and yearning for revenge; and Nikko, sometimes a living man, but always the ship's disembodied mind.

They are bound for unknown territory. Ahead of them loom vast, lightless clouds of dust and gas where stars are born, and where the alien Chenzeme are believed to live. The Chenzeme are an enigmatic race whose automated warships have ravaged the living worlds of the galaxy's Orion arm for millions of years. But why? Null Boundary's crew is driven to find out--though in their quest to discover the source of the Chenzeme, they must also explore the terrible truth of their own past, the meaning of revenge, and the price each one of them is willing to pay for survival. --This text refers to an out of print or unavailable edition of this title.

At last--the ultimate book in the renowned Heechee Saga! Advanced Heechee technology had enabled Robinette Broadhead to live after death as a machine-stored personality, enjoying his life by flitting along the wires from party to party with a host of other machine-people. But suddenly his decadent existence ends when an all powerful alien race intent on the utter destruction of all intelligent life reappears after eons of silence, and threatens the lives of all heechee and humans.

Even Robin, virtually immortal and with unlimited access to millennia of accumulated data, cannot discover how to stop these aliens. It began to seem that only a face to face meeting could determine the future of the entire universe....

One hundred years before Ender's Game, the aliens arrived on Earth with fire and death. This is the story of the First Formic War.

Victor Delgado beat the alien ship to Earth, but just barely. Not soon enough to convince skeptical governments that there was a threat. They didn't believe that until space stations and ships and colonies went up in sudden flame.

And when that happened, only Mazer Rackham and the Mobile Operations Police could move fast enough to meet the threat.

In the middle of the South Pacific, a thousand feet below the surface of the water, a huge vessel is discovered resting on the ocean floor. It is a spaceship of phenomenal dimensions, apparently undamaged by its fall from the sky. And, most startling, it appears to be at least three hundred years old.

But even more fantastic—and frightening—is what waits inside . . .

There is a dream called Moonbase, nurtured by ex-astronaut Paul Stavenger and his wife, Joanna Masterson Stavenger, head of the powerful Masterson Corporation.

There is a future of astonishing possibilities and vital technological development waiting on a lifeless world of astonishing contrasts, where sub-frigid darkness abuts the blood-boiling light -- a future threatened by greed and jealousy, insanity and murder.

The Moon and its mysteries have captivated the Stavenger family, and it will continue to exert its pull upon subsequent generations. For all those who experience its magnificent desolation are haunted by it eternally. Some will be doomed by its pitiless aversion to human life.

And some can never leave.

Once, Dan Randolph was one of the richest men on Earth. Now the planet is spiraling into environmental disaster, with floods and earthquakes destroying the lives of millions. Randolph knows the energy and natural resources of space can save Earth's economy, but the price may be the loss of the only thing he has left--the company he founded, Astro Manufacturing.

Martin Humphries, fabulously wealthy heir of the Humphries Trust, also knows that space-based industry is the way of the future. But unlike Randolph, he doesn't care if Earth perishes in the process. And he knows that the perfect bait to ensnare Dan Randolph--and take control of Astro--is his revolutionary new fusion propulsion system.

As Randolph--accompanied by two fascinating women who are also brilliant astronauts--flies out to the Asteroid Belt aboard a fusion-propelled spacecraft, Humphries makes his move. The future of mankind lies in Randolph's hands.

The Asteroid Wars have begun.

D. D. Harriman is a billionaire with a dream: the dream of Space for All Mankind. The method? Anything that works. Maybe, in fact, Harriman goes too far.

But he will give us the stars....

Fleet of Worlds marks Larry Niven's first full novel-length collaboration within his Known Space universe, the playground he created for his bestselling Ringworld series. Teaming up with fellow SF writer Edward M. Lerner, Fleet of Worlds takes a closer look at the Human-Puppeteer (Citizens) relations and the events leading up to Niven's first Ringworld novel.

Kirsten Quinn-Kovacs is among the best and brightest of her people. She gratefully serves the gentle race that rescued her ancestors from a dying starship, gave them a world, and nurtures them still. If only the Citizens knew where Kirsten's people came from....

A chain reaction of supernovae at the galaxy's core has unleashed a wave of lethal radiation that will sterilize the galaxy. The Citizens flee, taking their planets, the Fleet of Worlds, with them.

Someone must scout ahead, and Kirsten and her crew eagerly volunteer. Under the guiding eye of Nessus, their Citizen mentor, they explore for any possible dangers in the Fleet's path--and uncover long-hidden truths that will shake the foundations of worlds.

A starship hurtles through the emptiness of space. Its destination-unknown. Its purpose-a mystery.

Now, one man wakes up. Ripped from a dream of a new home-a new planet and the woman he was meant to love in his arms-he finds himself wet, naked, and freezing to death. The dark halls are full of monsters but trusting other survivors he meets might be the greater danger.

All he has are questions-- Who is he? Where are they going? What happened to the dream of a new life? What happened to Hull 03?

All will be answered, if he can survive the ship.

HULL ZERO THREE is an edge-of-your-seat thrill ride through the darkest reaches of space.

In the year 2130 a mysterious spaceship, Rama, arrived in the solar system. It was huge, but empty - apparently abandoned. By the time Rama departed for its next unknown destination many wonders had been uncovered, but few mysteries solved. Only one thing was clear: everything the enigmatic builders of Rama did, they did in threes.

Eighty years later the second alien craft arrived in the solar system. This time, Earth had been waiting. Now Rama II is on its way out of the solar system. Aboard it are three humans, two men and a woman, left behind when the expedition departed. Ahead of them lies the unknown, a voyage no human has ever experienced; and at the end of it may lie the truth about Rama.

On the North Pole of Pluto there stands an enigma: a huge circle of standing blocks of ice, built on the pattern of Earth's Stonehenge--but ten times the size, standing alone at the farthest reaches of the Solar System. What is it? Who came there to build it?

In Kim Stanley Robinson's Icehenge,the secret lies, perhaps, in the chaotic decades of the Martian Revolution, in the lost memories of those who have lived for centuries.

Also published as Year 2018!

2018 AD. The time of the Cold Peace, worse even than the Cold War. The bureaucratic regimes that rule from Washington and Moscow are indistinguishable in their passion for total repression. But in the West, a few dedicated individuals still struggle to find a way out of the trap of human history. Behind the screen of official research their desperate project is nearing completion...

The Tenebrans are intelligent, but primitive by human standards. Yet scientists from Earth have found ways to train and educate some of the Tenebrans. This training becomes crucial when two beings—a young girl from Earth and the son of an alien diplomat—are marooned in a bathyscape that is headed toward the surface of the planet, where neither can hope to survive.

When corporations go to war, standard business practice goes out the window. Astro Corporation is led by indomitable Texan Pancho Lane, Humphries Space Systems by the rich and ruthless Martin Humphries, and their fight is over nothing less than resources of the Asteroid Belt itself. As fighting escalates, the lines between commerce and politics, boardroom and bedroom, blur--and the keys to victory will include physics, nanotechnology, and cold hard cash.

As they fight it out, the lives of thousands of innocents hang in the balance, including the rock rats who make their living off the asteroids, and the inhabitants of Selene City on Earth's moon. As if matters weren't complicated enough, the shadowy Yamagata corporation sets its sights on taking advantage of other people's quarrels, and space pirate Lars Fuchs decides it's time to make good on his own personal vendetta.

It's a breakneck finale that can end only in earth's salvation--or the annihilation of all that humankind has ever accomplished in space.

2026: Something is growing in the Pacific Ocean, a strange fungus-like organism that may threaten our entire food chain. Christened "the slick," the bizarre phenomenon is quickly the subject of intense, top-secret analysis-which rapidly reveals that it contains DNA unlike that of any other life on the planet.

Where is it from? A Chinese mission to Mars is rumored to have discovered life beneath the Martian icecap, but the Chinese aren't talking. Dr. Mariella Anders is recruited by NASA to join an urgent mission to the Red Planet to find out. Brilliant and committed to science, Mariella wants only the truth, but others' motives are less noble. Faced with corporations, activist groups, and superpowers, each with their own secret agendas, Mariella is on a perilous quest for knowledge... and she's about the discover the high price of truth.

Second in size only to Jupiter, bigger than a thousand Earths but light enough to float in water, home of crushing gravity and delicate, seemingly impossible rings, it dazzles and attracts us:

SATURN

Earth groans under the thumb of fundamentalist political regimes. Crisis after crisis has given authoritarians the upper hand. Freedom and opportunity exist in space, for those with the nerve and skill to run the risks.

Now the governments of Earth are encouraging many of their most incorrigible dissidents to join a great ark on a one-way expedition, twice Jupiter's distance from the Sun, to Saturn, the ringed planet that baffled Galileo and has fascinated astronomers ever since.

But humans will be human, on Earth or in the heavens-so amidst the idealism permeating Space Habitat Goddard are many individuals with long-term schemes, each awaiting the right moment. And hidden from them is the greatest secret of all, the real purpose of this expedition, known to only a few....

When evidence of an advanced civilization is discovered by SETI astronomers, an expedition into the far reaches of the galaxy is planned and an eclectic team of scientists is chosen to make the trip. But because the origin of the alien signals is thousands of light-years away, the crew will age only a few years while millennia pass on Earth. And though they are ready to face the ramifications of such a voyage, none of the starfarers are prepared for what awaits them at the outer edge of the cosmos--or back at the planet they once called home.

Caine Riordan, reluctant diplomatic and military intelligence operative, has just finished playing his part repulsing the Arat Kur's and Hkh'Rkh's joint invasion of Earth.

But scant hours after the attackers surrender, the mysterious but potentially helpful Slaasriithi appeal to Caine to shepherd a diplomatic mission on a visit to their very alien worlds. The possible prize: a crucial alliance in a universe where the fledgling Consolidated Terran Republic has very few friends.

But Caine and his legation aren't the only ones journeying into the unknown reaches of Slaasriithi space. A group of renegade K'tor are following them, hoping to destroy humanity's hopes for a quick alliance. And that means finding and killing Caine Riordan.

Assuming that the bizarre and dangerous Slaasriithi lifeforms don't do it first.

Two hundred thousand feet up, things go horribly wrong. An experimental low-orbit spaceplane breaks up on reentry, falling to earth over a trail hundreds of miles long. And it its wake is the beginning of the most important mission in the history of space.

America needs energy, and Dan Randolph is determined to give it to them. He dreams of an array of geosynchronous powersats, satellites which gather solar energy and beam it to generators on Earth, freeing America from its addiction to fossil fuels and breaking the power of the oil cartels forever. But the wreck of the spaceplane has left his company, Astro Manufacturing, on the edge of bankruptcy.

Worse, Dan discovers that the plane worked perfectly right up until the moment that saboteurs knocked it out of the sky. And whoever brought it down is willing and able to kill again to keep Astro grounded.

Now Dan has to thread a dangerous maze. The visible threats are bad enough: Rival firms want to buy him out and take control of his dreams. His former lover wants to co-opt his unlimited-energy idea as a campaign plank for the candidate she's grooming for the presidency. NASA and the FAA want to shut down his maverick firm. And his creditors are breathing down his neck.

Making matters even more dangerous, an international organization of terrorists sees the powersat as a threat to their own oil-based power. And they've figured out how to use it as a weapon in their war against the West.

A sweeping mix of space, murder, romance, politics, secrets, and betrayal, Powersat will take you to the edge of space and the dawning of a new world.

In 3229 A.D., human civilization is scattered among the planets, moons, and asteroids of the solar system. Billions of lives depend on the technology derived from the breakthroughs of the greatest physicist of the age, Arthur Holywelkin. But in the last years of his life, Holywelkin devoted himself to building a strange, beautiful, and complex musical instrument that he called The Orchestra.

Johannes Wright has earned the honor of becoming the Ninth Master of Holywelkin's Orchestra. Follow him on his Grand Tour of the Solar System, as he journeys down the gravity well toward the sun, impelled by a destiny he can scarcely understand, and is pursued by mysterious foes who will tell him anything except the reason for their enmity.

Journey Across the Sea of Space

They named her Souther Cross and launched her on the road whose end they would never see. Months afterward shw was moving at half the speed of light; if there was to be enough reaction mass for deceleration and maneuver, the blast must be terminated. And so the long silence came. For four and half centuries the ship would fall.

They manned her by turns, and dreamed other ships and launched them, and saw how a few of the shortest journeys ended. Then they died.

After ten generations, the Souther Cross was not quite halfway to her own goal, though she was the farthest from Earth of any human work...

The Heechee were perhaps the greatest and most tantalizing mystery the human race had ever known. The first Heechee artifacts were uncovered on Venus, and in the beginning they were treated as nothing more than costly souvenirs and curiosities for tourists from Earth and Mars. But when an asteroid stocked with autonavigating spacecraft was discovered, suddenly the Heechee universe was thrown wide open, giving birth to the Gateway Corporation and bringing untold riches to the adventurers who risked the unknown to see where those Heechee spacecraft would take them. Many of those brave souls never returned. The ones who did brought back technological wonders that transformed life on Earth -- but of the Heechee themselves there was no sign...

The Gateway Trip, lavishly illustrated by artist Frank Kelly Freas, presents the tales of those perilous journeys and marvelous discoveries, as those intrepid pioneers followed the trail of the elusive Heechee and changed the course of human history forever!

Orson Scott Card and Aaron Johnston return to their Ender's Game prequel series with this first volume of an all-new trilogy about the Second Formic War in The Swarm.

The first invasion of Earth was beaten back by a coalition of corporate and international military forces, and the Chinese army. China has been devastated by the Formic's initial efforts to eradicate Earth life forms and prepare the ground for their own settlement. The Scouring of China struck fear into the other nations of the planet; that fear blossomed into drastic action when scientists determined that the single ship that wreaked such damage was merely a scout ship.

There is a mothership out beyond the Solar System's Kuiper Belt, and it's heading into the system, unstoppable by any weapons that Earth can muster.

Earth has been reorganized for defense. There is now a Hegemon, a planetary official responsible for keeping all the formerly warring nations in line. There's a Polemarch, responsible for organizing all the military forces of the planet into the new International Fleet. But there is an enemy within, an enemy as old as human warfare: ambition and politics. Greed and self-interest. Will Bingwen, Mazer Rackam, Victor Delgado and Lem Juke be able to divert those very human enemies in time to create a weapon that can effectively defend humanity in the inexorable Second Formic War?

Anu, red giant companion-star to Bel and Ea, was relentlessly approaching Ishtar-scorching the land, forcing the barbarians of the North ever southward away from the inferno. Fire Time was fast confronting the planet; civil war broke out as the Tassui led their forces against the army of the Gathering in a desperate struggle for survival.

The Gathering anxiously awaited help from the human colony in Primavera. Jill Conway and other colonists like her hoped to save the civilization of Ishtar and they relied on the Navy of the Federation of Earth to do so. But now the Federation was engaged in its own war with Naqsa, an interstellar war that seemingly had no end. And no end meant no help for Ishtar....

The Return of Barlennan

Dhrawn was a giant rock ball, more than 3,000 time the mass of Earth. Perhaps a planet, perhaps a nearly dead star, these 17 billion square miles of mystery cried out for investigation. But its corrosive atmosphere and crushing gravity assured that no human would ever set foot on its surface.

Those hardy, caterpillar-like Mesklinites, on the other hand, were ideally suited to explore Dhrawn, and their leader certainly knew a good deal when he saw one. So Barnennan, a shrewd sea captain if ever there was one, struck a sharp bargain with the Earth men for his services in leading the expedition.

But the humans might not have been so pleased with their side of the bargain, if they had known Barlennan had plans of his own for Dhrawn...

Hugo Award-winning editor, author, scientist, and journalist, Ben Bova is a modern master of near-future science fiction and a passionate advocate of manned space exploration. For more than a decade, Bova has been chronicling humanity's struggles to colonize our solar system in a series of interconnected novels known as "The Grand Tour."

Now, with Titan, Ben Bova takes readers to one of the most intriguing destinations in near space: the extraordinary moon of Saturn which made international headlines last year when the Huygens probe sent back remarkable images of its strange landscapes.

2095. After long months of travel, the gigantic colony ship Goddard has at last made orbit around Saturn, carrying a population of more than of 10,000 dissidents, rebels, extremists, and visionaries seeking a new life. Among Goddard's missions is the study of Titan, which offers the tantalizing possibility that life may exist amid its windswept islands and chill black seas.

When the exploration vessel Titan Alpha mysteriously fails after reaching the moon's surface, long buried tensions surface among the colonists. Eduoard Urbain, the mission's chief scientist, is wracked with anxiety and despair as he sees his life's work unravel. Malcolm Eberly, Goddard's chief administrator, takes ruthless measures to hold onto power as a rash of suspicious incidents threaten to undermine his authority. Holly Lane, the colony's human-resources director, must confront the station's powerful leaders to protect the lives of its people. And retired astronaut Manuel Gaeta is forced to risk his life in a last, desperate attempt to salvage the lost probe.

Torn by intrigue, sabotage, and an awesome discovery that could threaten human space exploration, a handful of courageous men and women must fight for the survival of their colony, and for the destiny of the human race.

In this exhilarating sequel to The Skylark of Space, momentous danger again stalks genius inventor and interplanetary adventurer Dr. Richard Seaton. Seaton's allies on the planet Kondal are suffering devastating attacks by the forces of the Third Planet. Even worse, the menacing and contemptuous Fenachrones are threatening to conquer the galaxy and wipe out all who oppose them. And don't forget the dastardly machinations of Seaton's arch-nemesis, DuQuesne, who embarks on a nefarious mission of his own. Against such vile foes and impossible odds, how is victory possible?

Featuring even more technological wizardry, alien worlds, and all-out action than its predecessor, Skylark Three is hailed by many as the imaginative high point of the Skylark series.

The final work from the brightest star in science fiction's galaxy. Arthur C Clarke, who predicted the advent of communication satellites and author of 2001: A Space Odyssey completes a lifetime career in science fiction with a masterwork.

30 light years away, a race known simply as the One Point Fives are plotting a dangerous invasion plan, one that will wipe humankind off the face of the Earth...

Meanwhile, in Sri Lanka, a young astronomy student, Ranjit Subramanian, becomes obsessed with a three-hundred-year-old theorem that promises to unlock the secrets of the universe. While Ranjit studies the problem, tensions grow between the nations of the world and a UN taskforce headed up by China, America and Russia code-named Silent Thunder begins bombing volatile regimes into submission.

On the eve of the invasion of Earth a space elevator is completed, helped in part by Ranjit, which will herald a new type of Olympics to be held on the Moon. But when alien forces arrive Ranjit is forced to question his own actions, in a bid to save the lives of not just his own family but of all of humankind.

Co-written with fellow grand master Frederik Pohl, The Last Theorem not only provides a fitting end to the career one of the most famous names in science fiction but also sets a new benchmark in contemporary prescient science fiction. It tackles with ease epic themes as diverse as third world poverty, the atrocities of modern warfare in a post-nuclear age, space elevators, pure mathematics and mankind's first contact with extra-terrestrials.

In this first collaboration by science fiction masters Larry Niven (Ringworld) and Gregory Benford (Timescape), the limits of wonder are redrawn once again as a human expedition to another star system is jeopardized by an encounter with an astonishingly immense artifact in interstellar space: a bowl-shaped structure half-englobing a star, with a habitable area equivalent to many millions of Earths...and it's on a direct path heading for the same system as the human ship.

A landing party is sent to investigate the Bowl, but when the explorers are separated--one group captured by the gigantic structure's alien inhabitants, the other pursued across its strange and dangerous landscape--the mystery of the Bowl's origins and purpose propel the human voyagers toward discoveries that will transform their understanding of their place in the universe.
