When nuclear war breaks out and the nations of the Earth are destroyed, a group of US astronauts are marooned on the lunar surface. Using the "torsion field generator", a WWII Nazi Wunderwaffe previously known as the Bell, they hope to find an alternate Earth that did not suffer nuclear armageddon. But once they do discover one, how will they return home? They have a single Lunar Module, which can carry only four astronauts into lunar orbit...

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?

Before becoming one of today's most intriguing and innovative mystery writers, Kate Wilhelm was a leading writer of science fiction, acclaimed for classics like The Infinity Box and The Clewiston Test.

Now one of her most famous novels returns to print, the spellbinding story of an isolated post-holocaust community determined to preserve itself, through a perilous experiment in cloning. Sweeping, dramatic, rich with humanity, and rigorous in its science, Where Later the Sweet Birds Sang is widely regarded as a high point of both humanistic and "hard" SF, and won SF's Hugo Award and Locus Award on its first publication. It is as compelling today as it was then.

Professor Edward Kitchener, a double Nobel laureate researching quantum cosmology for the powerful Event Horizon conglomerate, has been savagely murdered. But was he the victim of industrial espionage, personal revenge, or a crime of passion by one of his handpicked team of live-wire students?

Event Horizon needs to know, and fast, so Greg Mandel, PSI-boosted veteran of the infamous Mindstar Battalion, must embark on an urgent investigation that ultimately leads him to an astounding confrontation with a past, which, according to the dead man's theories, might never have happened.

Monumental devastation will sweep across the globe if the newly-discovered Hamner-Brown comet collides with the one major obstacle in its path: Earth.

For millionaire Tim Hamner, the comet is a ticket to immortality. For filmmaker Harvey Randall, it's a shot to redeem a flagging career. And for astronauts John Baker and Rick Delanty, it's a second chance for glory in outer space.

But for a world gripped by comet fever, fascination quickly turns to fear. And only those who survive the impact will know the even greater terror, when rich and poor, politicians and killers, turn to each other or against each other--and the remnants of humanity grow savage to battle for what little remains...

The 21st century was on the brink of nuclear confrontation when the 300 kilometer-long stone flashed out of nothingness and into Earth's orbit. NASA, NATO, and the UN sent explorers to the asteroid's surface...and discovered marvels and mysteries to drive researchers mad.

For the Stone was from space--but perhaps not our space; it came from the future--but perhaps not our future; and within the hollowed asteroid was Thistledown. The remains of a vanished civilization. A human--English, Russian, and Chinese-speaking--civilization. Seven vast chambers containing forests, lakes, rivers, hanging cities...

And museums describing the Death; the catastrophic war that was about to occur; the horror and the long winter that would follow. But while scientists and politicians bickered about how to use the information to stop the Death, the Stone yielded a secret that made even Earth's survival pale into insignificance.

Vortex tells the story of Turk Findley, the protagonist introduced in Axis, who is transported ten thousand years into the future by the mysterious entities called "the Hypotheticals." In this future humanity exists on a chain of planets connected by Hypothetical gateways; but Earth itself is a dying world, effectively quarantined.

Turk and his young friend Isaac Dvali are taken up by a community of fanatics who use them to enable a passage to the dying Earth, where they believe a prophecy of human/Hypothetical contact will be fulfilled. The prophecy is only partly true, however, and Turk must unravel the truth about the nature and purpose of the Hypotheticals before they carry him on a journey through warped time to the end of the universe itself.

What would happen if the world were ending?

A catastrophic event renders the earth a ticking time bomb. In a feverish race against the inevitable, nations around the globe band together to devise an ambitious plan to ensure the survival of humanity far beyond our atmosphere, in outer space.

But the complexities and unpredictability of human nature coupled with unforeseen challenges and dangers threaten the intrepid pioneers, until only a handful of survivors remain...

Five thousand years later, their progeny -- seven distinct races now three billion strong--embark on yet another audacious journey into the unknown... to an alien world utterly transformed by cataclysm and time: Earth.

On September 28th, a geologist working in Death valley finds a mysterious new cinder cone in very well-mapped area.

On October 1st, the government of Australia announces the discovery of an enormous granite mountain. Like the cinder cone, it wasn't there six months ago....

Something is happening to Planet Earth, and the truth is too terrifying to consider....

When the planet of Moscow was annihilated, its few survivors launched a counter-attack against the most likely culprit: the neighboring system of New Dresden. But New Dresden wasn't responsible, and as the deadly missiles approach their target, Rachel Mansour, agent for the interests of Old Earth, is assigned to find out who was.

And the one person who knows is a disaffected teenager who calls herself Wednesday Shadowmist. But Wednesday has no idea what she knows...

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.

For three generations, the Macz family has struggled to cope with the rampant technological achievements that have rendered humans near obsolete. And mankind's end encroaches even closer when something starts to dismantle the nine planets of the solar system in an effort to annihilate all biological lifeforms.

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...

An amazing breakthrough in genetic engineering made by Vergil Ulam is considered too dangerous for further research, but rather than destroy his work, he injects himself with his creation and walks out of his lab, unaware of just quite how his actions will change the world. Author Greg Bear's treatment of the traditional tale of scientific hubris is both suspenseful and a compelling portrait of a new intelligence emerging amongst us, irrevocably changing our world.

It's fifty years from tomorrow, and a black hole has accidentally fallen into the Earth's core. A team of scientists frantically searches for a way to prevent the mishap from causing harm, only to discover another black hole already feeding relentlessly at the core - one that could destroy the entire planet within two years.

But some even argue that the only way to save the Earth is to let its human inhabitants become extinct: to let the million-year evolutionary clock rewind and start all over again.

From an underground lab in New Zealand to a space station in Low Earth Orbit, from an endangered species conservation ark in Africa to a home in New Orleans, EARTH is a gripping novel peopled with extraordinary characters and abundant with challenging new ideas. Above all, it is an impassioned testament about our own responsibility to our endangered planet.

The story came about when, in 1988, Marty Greenberg suggested Asimov find someone who would take his forty-seven year old short story, "Nightfall", and - keeping the story essentially as written - add a detailed beginning and a detailed ending to it. This resulted in the 1990 publication of the novel, Nightfall by Isaac Asimov and Robert Silverberg. As Asimov relates in the Robert Silverberg chapter of his autobiography, "...Eventually, I received the extended Nightfall manuscript from Bob [Silverberg]... Bob did a wonderful job and I could almost believe I had written the whole thing myself. He remained absolutely faithful to the original story and I had very little to argue with.

These two renowned writers have invented a world not unlike our own--a world on the edge of chaos, torn between the madness of religious fanaticism and the stubborn denial of scientists. Only a handful of people on the planet Lagash are prepared to face the truth--that their six suns are setting all at once for the first time in 2,000 years, signaling the end of civilization!

Prepare for a different kind of singularity in Peter Watts' Echopraxia, the follow-up to the Hugo-nominated novel Blindsight.

It's the eve of the twenty-second century: a world where the dearly departed send postcards back from Heaven and evangelicals make scientific breakthroughs by speaking in tongues; where genetically engineered vampires solve problems intractable to baseline humans and soldiers come with zombie switches that shut off self-awareness during combat. And it's all under surveillance by an alien presence that refuses to show itself.

Daniel Bruks is a living fossil: a field biologist in a world where biology has turned computational, a cat's-paw used by terrorists to kill thousands. Taking refuge in the Oregon desert, he's turned his back on a humanity that shatters into strange new subspecies with every heartbeat. But he awakens one night to find himself at the center of a storm that will turn all of history inside-out.

Now he's trapped on a ship bound for the center of the solar system. To his left is a grief-stricken soldier, obsessed by whispered messages from a dead son. To his right is a pilot who hasn't yet found the man she's sworn to kill on sight. A vampire and its entourage of zombie bodyguards lurk in the shadows behind. And dead ahead, a handful of rapture-stricken monks takes them all to a meeting with something they will only call "The Angels of the Asteroids."

Their pilgrimage brings Dan Bruks, the fossil man, face-to-face with the biggest evolutionary breakpoint since the origin of thought itself.

The Peace War is quintessential hard-science adventure. The Peace Authority conquered the world with a weapon that never should have been a weapon--the "bobble," a spherical force-field impenetrable by any force known to mankind. Encasing governmental installations and military bases in bobbles, the Authority becomes virtually omnipotent. But they've never caught Paul Hoehler, the maverick who invented the technology, and who has been working quietly for decades to develop a way to defeat the Authority.

With the help of an underground network of determined, independent scientists and a teenager who may be the apprentice genius he's needed for so long, he will shake the world, in the fast-paced hard-science thriller that garnered Vinge the first of his four Hugo nominations for best novel.

In the twenty-first century man created the Eschaton, a sentient artificial intelligence. It pushed Earth through the greatest technological evolution ever known, while warning that time travel is forbidden, and transgressors will be eliminated. Distant descendants of this ultra high-tech Earth live in parochial simplicity on the far-flung worlds of the New Republic. Their way of life is threatened by the arrival of an alien information plague known as the Festival. As forbidden technologies are literally dropped from the sky, suppressed political factions descend into revolutionary turmoil. A battle fleet is sent from Earth to destroy the Festival, but Spaceship engineer Martin Springfield and U.N. diplomat Rachel Mansour have been assigned rather different tasks. Their orders are to diffuse the crisis or to sabotage the New Republic's war-fleet, whatever the cost, before the Eschaton takes hostile action on a galactic scale.

Greg Mandel, late of the Mindstar Battalion, has been many things in his life. Commando. Freedom fighter. Assassin. Now he's a freelance operative with a very special edge: telepathy.

In the high-tech, hard-edged world of computer crime, zero-gravity smuggling, and artificial intelligence, Greg Mandel is the man to call when things get rough. But when an elusive saboteur plagues a powerful organization known as Event Horizon, Mandel must cut his way through a maze of corporate intrigue and startling new scientific discoveries.

And nothing less than the future is at stake.

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 ...

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.

Earth was dying...

One fourth of its population was dead. The rest had little time to live.

A mass of interstellar matter had invaded the solar system, fling planets out of orbit and blocking off the sun. In that titanic disaster, Man had one small chance to survive: Appeal to an alien intelligence that might exist and that might - or might not - care enough to help!

The bestselling author of the classic Mars trilogy and The Years of Rice and Salt returns with a riveting new trilogy of cutting-edge science, international politics, and the real-life ramifications of global warming as they are played out in our nation’s capital—and in the daily lives of those at the center of the action. Hauntingly realistic, here is a novel of the near future that is inspired by scientific facts already making headlines.

When the Arctic ice pack was first measured in the 1950s, it averaged thirty feet thick in midwinter. By the end of the century it was down to fifteen. One August the ice broke. The next year the breakup started in July. The third year it began in May. That was last year.

It’s an increasingly steamy summer in the nation’s capital as Senate environmental staffer Charlie Quibler cares for his young son and deals with the frustrating politics of global warming. Charlie must find a way to get a skeptical administration to act before it’s too late—and his progeny find themselves living in Swamp World. But the political climate poses almost as great a challenge as the environmental crisis when it comes to putting the public good ahead of private gain.

While Charlie struggles to play politics, his wife, Anna, takes a more rational approach to the looming crisis in her work at the National Science Foundation. There a proposal has come in for a revolutionary process that could solve the problem of global warming—if it can be recognized in time. But when a race to control the budding technology begins, the stakes only get higher. As these everyday heroes fight to align the awesome forces of nature with the extraordinary march of modern science, they are unaware that fate is about to put an unusual twist on their work—one that will place them at the heart of an unavoidable storm.

With style, wit, and rare insight into our past, present, and possible future, this captivating novel propels us into a world on the verge of unprecedented change—in a time quite like our own. Here is Kim Stanley Robinson at his visionary best, offering a gripping cautionary tale of progress—and its price—as only he can tell it.

Carmen Dula and her husband have spent six years traveling to a distant solar system that is home to the enigmatic, powerful race known as "The Others," in the hopes of finding enough common purpose between their species to forge a delicate truce.

By the time Carmen and her party return, fifty years have been consumed by relativity-and the Earthlings have not been idle, building a massive flotilla of warships to defend Earth against The Others. But The Others have their own plans.

Compelling, challenging and resilient, over ten beautifully contained chapters, Clade canvasses three generations from the very near future to late this century. Central to the novel is the family of Adam, a scientist, and his wife Ellie, an artist.

Clade opens with them wanting a child and Adam in a quandary about the wisdom of this. Their daughter proves to be an elusive little girl and then a troubled teenager, and by now cracks have appeared in her parents' marriage. Their grandson is in turn a troubled boy, but when his character reappears as an adult he's an astronomer, one set to discover something astounding in the universe.

With great skill James Bradley shifts us subtly forward through the decades, through disasters and plagues, miraculous small moments and acts of great courage. Elegant, evocative, understated and thought-provoking, it is the work of a writer in command of the major themes of our time.

Ellen May Ngewthu is a young woman with centuries of experience, a soldier and leader of the Cassini Division, the elite defense force of the utopian Solar Union. Here in the twenty-fourth century, the forts of the Division, in orbit around a mysteriously transformed Jupiter, are the front line in humanity's long standoff with the unknowable posthumans--godlike and remote beings descended from the people who transformed themselves with high technology centuries ago.

The posthumans' capacities are unknown . . . but we know they disintegrated Ganymede, we know they punched a wormhole into Jovian space, and we know that the very surface of the solar system's largest planet has been altered by their incomprehensible artifacts. Worst of all, we know that they have been bombarding the solar system with powerful data viruses for generations.

Now Ellen has a plan to rid humanity of this threat once and for all. But she needs to recruit the right people to her cause--and convince them to mistrust the posthumans as much as she does.

Her quest will take her to the mid-Atlantic towers of Solar Union Earth, to the green ruins of London, and, in the farthest reaches of human space, to the long-separated libertarian colony of New Mars. In the process, much will be revealed--about history, about power, and about what it is to be human.

Disgraced government operative Colonel Chu is exiled to the flooded relic of New York City. Something called the Light has hit the streets like an epidemic, leavings its users strung out and disconnected from the mind-network humanity relies on. Chu has lost everything she cares about to the Light. She'll end the threat or die trying.

A former corporate pilot who controlled a thousand ships with her mind, Zola looks like just another Light-junkie living hand to mouth on the edge of society. She's special though. As much as she needs the Light, the Light needs her too. But, Chu is getting close and Zola can't hide forever.

At the end of Frank Herbert's final novel, Chapterhouse: Dune, a ship carrying a crew of refugees escapes into the uncharted galaxy, fleeing from a terrifying, mysterious Enemy. The fugitives used genetic technology to revive key figures from Dune's past--including Paul Muad'Dib and Lady Jessica--to use their special talents to meet the challenges thrown at them.

Based directly on Frank Herbert's final outline, which lay hidden in two safe-deposit boxes for a decade, Sandworms of Dune will answer the urgent questions Dune fans have been debating for two decades: the origin of the Honored Matres, the tantalizing future of the planet Arrakis, the final revelation of the Kwisatz Haderach, and the resolution to the war between Man and Machine. This breathtaking new novel in Frank Herbert's Dune series has enough surprises and plot twists to please even the most demanding reader.

When a giant meteor crashes into the earth and destroys all life, the small group of human survivors manage to leave the barren planet and establish a new home on the moon. From Tycho Base, men and woman are able to observe the devastated planet and wait for a time when return will become possible.

Generations pass. Cloned children have had children of their own, and their eyes are raised toward the giant planet in the sky which long ago was the cradle of humanity. Finally, after millennia of waiting, the descendants of the original refugees travel back to a planet they've never known, to try and rebuild a civilization of which they've never been a part.

The fate of the earth lies in the success of their return, but after so much time, the question is not whether they can rebuild an old destroyed home, but whether they can learn to inhabit an alien new world--Earth.
