Foreigner: Arc 2: Book 3

C. J. Cherryh

It has been nearly ten years since the starship Phoenix retuned to the abandoned station orbiting the world of the alien atevi. This station, called Alpha, had been deserted for centuries following a rift between a faction of the station's inhabitants and the spacers' autocratic Pilot's Guild. For two hundred years this splinter faction had shared a fragile coexistence with the atevi, living in isolation on the island of Mospheira, communicating with the brilliant but volatile atevi by the use of a single highly trained diplomat, the paidhi, and trading technological information for continued peace and safety.

The unexpected return of the Phoenix has forever changed the lives of both atevi and Mospheirans, for over the ensuing decade, the captains of the Phoenix have brought both the atevi and their human counterparts into space. Their motivation seemed simple: Reunion Station, a human station in another sector of space, had been destroyed by aliens.

But on his deathbed, the senior captain of the Phoenix admits that he lied to the crew - that Reunion was merely damaged, not destroyed, and many people, including family and friends of the Phoenix crew may have survived. At this disclosure, the crew rebels and forces the Phoenix to undertake a rescue mission to Reunion.

But the crew and captains do not go alone, for on board are Bren Cameron, brilliant human paidhi, now representing Tabini-aiji, the atevi ruler, and Tabini's grandmother Ilisidi, the aiji-dowager, a fearsome, wily, and ambitious atevi leader with an agenda of her own.

Trapped in a distant star system with very little fuel left, facing a potentially bellicose alien ship, how can Bren help to avoid interspecies war when the notoriously secretive Pilot's Guild aboard Reunion Station won't even cooperate with their own ship, and may have kept the inhabitants of their own station ignorant of their true situation?

Intruder

Foreigner: Arc 5: Book 1

C. J. Cherryh

Civil war on the world of the atevi seems to be over, but diplomatic disputes and political infighting continue unabated. Bren Cameron, brilliant human diplomat allied with the dominant Western Association, has just returned to the capital from his country home on the coast. But his sojourn was anything but restful. Attacked by rebel forces hoping to kill not only him, but also Ilisidi, the grandmother, and Cajieri, the young son, of Tabini-aiji, the powerful head of the Western Association, Bren and his resourceful associates have had a small war of their own to contend with. And this small war has ended with a daring proposition: that their longtime enemy Machigi, having been double-crossed by his allies and approached by Ilisidi with an offer of alliance, will sign a trade agreement with her Eastern district-a situation which has upset both the rebels and the loyal north.

But Bren's accustomed role as negotiator for Tabini, Ilisidi, and their associates has suddenly changed radically—for Machigi, to Bren's utter shock, has evoked an ancient law. Bren wears the white ribbon that for the last few centuries has identified the single official human-atevi negotiator. But before humans landed, this white ribbon represented a specialized negotiator between atevi adversaries—a mediator who agreed to represent both sides with equal loyalty. These ancient mediators frequently ended up dead.

Now back in the capital, Bren finds that things are even more complicated than they previously were. He has now been put in the precaroius position of representing both Ilisidi and Machigi to the congress, and is becoming embroiled with both conservative and liberal factions. Meanwhile, Tabini-aiji is enraged to have lost the personal negotiator who has been his associate for decades, and is also jealous of any other party who stands to influence his young son. But there are even more dangerous things afoot, for Bren's bodyguard has warned him there is a crisis inside the immensely dangerous Assassins' Guild, and that the recent dustup with the Shadow Guild, a rebellious faction within the Assassins, may be only the beginning.

Inheritor

Foreigner: Arc 1: Book 3

C. J. Cherryh

Six months have passed since the reappearance of the starship Phoenix - six months during which the alien atevi have striven to reconfigure their fledling space program in a breakneck bid to take their place in the heavens alongside humans. But the return of the Phoenix has added a frighteningly powerful third party to an already volatile situation, polarizing political factions in both human and atevi societies, and making the possibility of all-out planetary war an ever more likely threat.

On the atevi mainland, human ambassador Bren Cameron, in a desperate attempt to maintain the peace, has arranged for one human representative from the Phoenix to take up residence with him in his apartments, while another is stationed on Mospheira, humanity's island enclave. Bren himself is unable to return home for fear of being arrested or assassinated by the powerful arch conservative element who wish to bar the atevi from space.

Responsible for a terrified, overwhelmed young man, and desperately trying to keep abreast of the political maneuverings of the atevi associations, how can Bren Cameron possibly find a way to save two species from a three-sided conflict that no one can win?

Blindsight

Blindsight: Book 1

Peter Watts

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...

But behind the scenes, a complex plot is unfolding, with the destruction of Holden at its core. As the emissaries of the human race try to find whether the gate is an opportunity or a threat, the greatest danger is the one they brought with them.

Hundreds of years later Lilith awakes, deep in the hold of a massive alien spacecraft piloted by the Oankali-who arrived just in time to save humanity from extinction. They have kept Lilith and other survivors asleep for centuries, as they learned whatever they could about Earth. Now it is time for Lilith to lead them back to her home world, but life among the Oankali on the newly resettled planet will be nothing like it was before.

The Oankali survive by genetically merging with primitive civilizations-whether their new hosts like it or not. For the first time since the nuclear holocaust, Earth will be inhabited.

John Wyndham

In the sleepy English village of Midwich, a mysterious silver object appears and all the inhabitants fall unconscious. A day later the object is gone and everyone awakens unharmed – except that all the women in the village are discovered to be pregnant.

The Dark Forest

Remembrance of Earth's Past: Book 2

Cixin Liu

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.

Chocky

John Wyndham

At first they thought that Matthew was just goining through a phase of talking to himself. And like many parents, they waited for him to grow out of it. But as time passed it became worse, not better. Matthew's conversations with himself grew more and more intense. It was like listening to one end of a telephone conversation while someone argued, cajoled and reasoned with another person you couldn't hear or see. Then Matthew began doing things he couldn't do before. Like counting in binary code mathematics. So he told them about Chocky, the person who lived in his head. Whoever or whatever Chocky was, it wasn't childish imagination. It was far too intelligent and frightening for that.

In a society where assassination is a recognised form of negotiation, Bren Cameron had been performing his task as Paidhi well.

Then the Phoenix returns, almost two hundred years after its departure.

Recovering from surgery on Mospheira, Cameron must return immediately to the atevi, but he finds his government has already sent a successor, Deanna Hanks, without informing him. And she has managed to alienate major factions against humanity.

Jodahs is supposed to be just another hybrid of human and Oankali, but as he begins his transformation to adulthood he finds himself becoming ooloi-the first ever born to a human mother. As his body changes, Jodahs develops the ability to shapeshift, manipulate matter, and cure or create disease at will. If this frightened young man is able to master his new identity, Jodahs could prove the savior of what's left of mankind. Or, if he is not careful, he could become a plague that will destroy this new race once and for all.

Who Goes There?

Hyperion Classics of Science Fiction: Book 44

John W. Campbell, Jr.

"Who Goes There?": The novella that formed the basis of "The Thing" is the John W. Campbell classic about an antarctic research camp that discovers and thaws the ancient body of a crash-landed alien. The creature revives with terrifying consequences, shape-shifting to assume the exact form of animal and man, alike.

Paranoia ensues as a band of frightened men work to discern friend from foe, and destroy the menace before it challenges all of humanity!

The story, hailed as "one of the finest science fiction novellas ever written" by the SF Writers of America, is best known to fans as THE THING - it was the basis of Howard Hawks' The Thing From Another World in 1951, and John Carpenter's The Thing in 1982.

The Puppet Masters

Robert A. Heinlein

First came the news that a flying saucer had landed in Iowa. Then came the announcement that the whole thing was a hoax. End of story. Case closed.

Except that two agents of the most secret intelligence agency in the U.S. government were on the scene and disappeared without reporting in. And four more agents who were sent in also disappeared. So the head of the agency and his two top agents went in and managed to get out with their discovery: an invasion is underway by slug-like aliens who can touch a human and completely control his or her mind. What the humans know, they know. What the slugs want, no matter what, the human will do. And most of Iowa is already under their control.

Sam Cavanaugh was one of the agents who discovered the truth. Unfortunately, that was just before he was taken over by one of the aliens and began working for the invaders, with no will of his own. And he has just learned that a high official in the Treasury Department is now under control of the aliens. Since the Treasury Department includes the Secret Service, which safeguards the President of the United States, control of the entire nation is near at hand . . .

The Dreaming Jewels

Theodore Sturgeon

Retro Hugo-nominated Novella

Theodore Sturgeon's stunning debut novel, about a young boy who is drawn into a dangerous conspiracy when he leaves home to join a circus of shadows

Though only eight years old, little Horton "Horty" Bluett has known a lifetime of sadness. Tormented and abused by his adoptive family, he's had enough—and with a beloved broken toy he calls "Junky" as his sole companion, the desperate little boy runs away to join a carnival. There, among the fortune tellers, fire-eaters, sideshow freaks, and assorted "strange people," Horty hopes to find acceptance and, at long last, a real home.

But disgraced doctor Pierre "Maneater" Monetre's traveling show is no ordinary entertainment, and its performers are not what they appear to be. The Maneater has sinister plans for the world that go far beyond fleecing unsuspecting rubes and other easy marks—a dark and terrible scheme that requires unleashing the extraterrestrial power of the dreaming jewels, and the unwitting assistance of a young boy who may be far more remarkable than he's ever imagined.

This ebook features an illustrated biography of Theodore Sturgeon including rare images and never-before-seen documents from the University of Kansas's Kenneth Spencer Research Library and the author's estate, among other sources.

On a warm March night in 2083, Judy Wallach-Stevens wakes to a warning of unknown pollutants in the Chesapeake Bay. She heads out to check what she expects to be a false alarm?and stumbles upon the first alien visitors to Earth. These aliens have crossed the galaxy to save humanity, convinced that the people of Earth must leave their ecologically-ravaged planet behind and join them among the stars. And if humanity doesn't agree, they may need to be saved by force.

The First Men in the Moon

H. G. Wells

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 Gripping Hand

The Moties: Book 2

Larry Niven
Jerry Pournelle

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.

Helliconia Summer

Helliconia: Book 2

Brian W. Aldiss

A planet orbiting binary suns, Helliconia has a Great Year spanning three millennia of Earth time: cultures are born in spring, flourish in summer, then die with the onset of the generations-long winter.

It is the summer of the Great Year on Helliconia. The humans are involved with their own affairs. Their old enemies, the phagors, are comparatively docile at this time of year, yet they can afford to wait, to take advantage of human weakness?and the king?s weakness. How they do so brings to a climax this powerfully compelling novel, in which the tortuous unwindings of circumstance enmesh royalty and commoners alike, and involve the Helliconia continents.

This is the second volume of the Helliconia Trilogy?a monumental saga that goes beyond anything yet created by this master among today?s imaginative writers.

Rollback

Robert J. Sawyer

Dr. Sarah Halifax decoded the first-ever radio transmission received from aliens. Thirty-eight years later, a second message is received and Sarah, now 87, may hold the key to deciphering this one, too... if she lives long enough.

A wealthy industrialist offers to pay for Sarah to have a rollback-a hugely expensive experimental rejuvenation procedure. She accepts on condition that Don, her husband of sixty years, gets a rollback, too. The process works for Don, making him physically twenty-five again. But in a tragic twist, the rollback fails for Sarah, leaving her in her eighties.

While Don tries to deal with his newfound youth and the suddenly vast age gap between him and his wife, Sarah struggles to do again what shed done once before: figure out what a signal from the stars contains.

Wave Without a Shore

Alliance-Union: Book 2

C. J. Cherryh

Freedom was an isolated planet, off the spaceways track and rarely visited by commercial spacers. It wasn't that Freedom was inhospitable as planets go. The problem was that outsiders – tourists and traders – claimed the streets were crowded with mysterious characters in blue robes and with members of an alien species.

Native-born humans, however, said that was not the case. There were no such blue-robes and no aliens. Such was the viewpoint of both Herrin the artist and Waden the autocrat – until a crisis of planetary identity forced a life-and-death confrontation between the question of reality and the reality of the question...

War Dogs

War Dogs: Book 1

Greg Bear

The Gurus came in peace, bearing gifts.

They were a highly advanced, interstellar species who brought amazingly useful and sophisticated technology to the human race. There was, of course, a catch. The Gurus warned of a far more malevolent life form, beings who have hounded the Gurus from sun to sun, planet to planet, across the cosmos. Pundits have taken to calling them the Antagonists - or Antags - and they have already established a beachhead on Mars. In exchange for all they've done for us, the Gurus would now like our help.

Enter Master Sergeant Michael Venn, a veteran Skyrine (a Marine who is specially trained for off-world combat) who is dropped onto the Red Planet with his band of brothers on a mission to take down as many Antags as possible.

But from the moment they're dropped through the thin Martian atmosphere, their mission goes horribly, terribly wrong. From a group of female special ops Skyrines with secret orders, to mysterious humans who've settled on Mars, to the overwhelming and highly-reinforced Antags themselves, Venn and his brothers will face impossible odds just to survive - let alone make it home alive.

Sphere

Michael Crichton

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.

When her Field Base is mysteriously attacked, Dr. Mackenzie Connor must flee for her life. Joining forces with an alien archaeologist, she escapes to his planet on a quest to find a defense against the unknown agressor before they launch a full-scale invasion of Earth.

Lagoon

Nnedi Okorafor

When a massive object crashes into the ocean off the coast of Lagos, Nigeria's most populous and legendary city, three people wandering along Bar Beach (Adaora, the marine biologist- Anthony, the rapper famous throughout Africa- Agu, the troubled soldier) find themselves running a race against time to save the country they love and the world itself... from itself. Lagoon expertly juggles multiple points of view and crisscrossing narratives with prose that is at once propulsive and poetic, combining everything from superhero comics to Nigerian mythology to tie together a story about a city consuming itself.

At its heart a story about humanity at the crossroads between the past, present, and future, Lagoon touches on political and philosophical issues in the rich tradition of the very best science fiction, and ultimately asks us to consider the things that bind us together--and the things that make us human.

There was no time to flee. No time to turn. No time to shriek. And there was no pain. It was like being thrown into the stars.

The Star Beast

Heinlein Juveniles: Book 8

Robert A. Heinlein

Lummox had been the Stuart family pet for years. Though far from cuddly and rather large, it had always been obedient and docile. Except, that is, for the time it had eaten the secondhand Buick . . .

But now, all of a sudden and without explanation, Lummox had begun chomping down on a variety of things -- not least, a very mean dog and a cage of virtually indestructible steel. Incredible!

John Thomas and Lummox were soon in awfully hot water, and they didn't know how to get out. And neither one really understood just how bad things were -- or how bad the situation could get -- until some space voyagers appeared and turned a far-from-ordinary family problem into an extraordinary confrontation.

Armada

Ernest Cline

Zack Lightman has spent his life dreaming. Dreaming that the real world could be a little more like the countless science-fiction books, movies, and videogames he's spent his life consuming. Dreaming that one day, some fantastic, world-altering event will shatter the monotony of his humdrum existence and whisk him off on some grand space-faring adventure.

But hey, there's nothing wrong with a little escapism, right? After all, Zack tells himself, he knows the difference between fantasy and reality. He knows that here in the real world, aimless teenage gamers with anger issues don't get chosen to save the universe.

And then he sees the flying saucer.

Even stranger, the alien ship he's staring at is straight out of the videogame he plays every night, a hugely popular online flight simulator called Armada--in which gamers just happen to be protecting the earth from alien invaders.

No, Zack hasn't lost his mind. As impossible as it seems, what he's seeing is all too real. And his skills--as well as those of millions of gamers across the world--are going to be needed to save the earth from what's about to befall it.

It's Zack's chance, at last, to play the hero. But even through the terror and exhilaration, he can't help thinking back to all those science-fiction stories he grew up with, and wondering: Doesn't something about this scenario seem a little... familiar?

At once gleefully embracing and brilliantly subverting science-fiction conventions as only Ernest Cline could, Armada is a rollicking, surprising thriller, a classic coming of age adventure, and an alien invasion tale like nothing you've ever read before--one whose every page is infused with the pop-culture savvy that has helped make Ready Player One a phenomenon.

Killing Titan

War Dogs: Book 2

Greg Bear

After barely surviving his last tour on Mars, Master Sergeant Michael Venn finds himself back on earth in enforced isolation. Through a dangerous series of operations he returns to Mars to further his investigation into the Drifters - ancient artifacts suddenly reawakened on the red planet.

But another front in the war leads his team to make the difficult journey to Saturn's moon, Titan. Here, in the cauldron of war, hides new truths about the Drifters, the origin of life in our solar system and the plans of the supposedly benevolent Gurus, who have been "sponsoring" and supporting humanity in their fight against outside invaders.

Killing Titan is the second book in the epic interstellar War Dogs trilogy from master of science fiction, Greg Bear.

Terra Nullius

Claire G. Coleman

"Jacky was running. There was no thought in his head, only an intense drive to run. There was no sense he was getting anywhere, no plan, no destination, no future. All he had was a sense of what was behind, what he was running from. Jacky was running."

The Natives of the Colony are restless. The Settlers are eager to have a nation of peace, and to bring the savages into line. Families are torn apart, reeducation is enforced. This rich land will provide for all.

This is not Australia as we know it. This is not the Australia of our history books. This TERRA NULLIUS is something new, but all too familiar.

This is an incredible debut from a striking new Australian Aboriginal voice.

White Queen

The Aleutian Trilogy: Book 1

Gwyneth Jones

In the year 2038, the earth has been ravaged by earthquakes and volcanic eruptions. Retroviruses run rampant through humanity. Economic disaster has destabilised the world, the US has undergone a socialist revolution, and the balance of power has changed.

Then the aliens arrive.

With no clear understanding of the visitors' intent, factions form, including the anti-alien group White Queen, working to turn humans against these extra-terrestrial tourists. Caught in the middle is Johnny Guglio, an American exile whose only fault was living near the landing site, and Braemar Wilson, a cutthroat reporter who will do whatever she needs to get ahead of the story. And for better or for worse, it seems being caught in the middle is the best place for them to uncover the truth.

The Last Theorem

Arthur C. Clarke
Frederik Pohl

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.
