A Fire Upon the Deep

Zones of Thought: Book 1

Vernor Vinge

Thousands of years hence, many races inhabit a universe where a mind's potential is determined by its location in space, from superintelligent entities in the Transcend, to the limited minds of the Unthinking Depths, where only simple creatures and technology can function. Nobody knows what strange force partitioned space into these "regions of thought," but when the warring Straumli realm use an ancient Transcendent artifact as a weapon, they unwittingly unleash an awesome power that destroys thousands of worlds and enslaves all natural and artificial intelligence.

Fleeing the threat, a family of scientists, including two children, are taken captive by the Tines, an alien race with a harsh medieval culture, and used as pawns in a ruthless power struggle. A rescue mission, not entirely composed of humans, must rescue the children-and a secret that may save the rest of interstellar civilization.

The Prefect

Revelation Space: Prefect Dreyfus Emergency: Book 1

Alastair Reynolds

Tom Dreyfus is a Prefect, a law enforcement officer with the Panoply. His beat is the multi-faceted utopian society of the Glitter Band, that vast swirl of space habitats orbiting the planet Yellowstone, the teeming hub of a human interstellar empire spanning many worlds.

His current case: investigating a murderous attack against one of the habitats that leaves nine hundred people dead, a crime that appalls even a hardened cop like Dreyfus. But then his investigation uncovers something even more potentially dangerous-a covert plot by an enigmatic entity seeking nothing less than total control of the Glitter Band...

The Rise of Endymion

The Hyperion Cantos: Book 4

Dan Simmons

In The Rise of Endymion, Dan Simmons brings to a triumphant conclusion one of the most celebrated, compelling, and dramatic science fiction sagas of our time. Brilliant, provocative, unfailingly inventive, the odyssey began with the Hugo Award-winning Hyperion, continued through the critically acclaimed The Fall of Hyperion and Endymion, and now ascends to its greatest heights yet....

The final chapter of this magnificent saga begins with two momentous events: the death and resurrection of Pope Julius XV and the coming-of-age of the new messiah. Her name is Aenea and she is the only person who can counter the pope and his plan to unleash the Pax Fleet, the Church's military wing, on a final genocidal Crusade to gain total dominion over the universe. The Church is allied with the infamous AI Core, which has offered immortality to humankind--or at least to those faithful who pledge total obedience to the Church--but at what terrible price? The Core has its own dark motives and secrets, and only Aenea knows what they are.

Aenea, too, has an ally. Her protector, Raul Endymion, onetime shepherd and convicted murderer, finds her in exile undergoing a strange apprenticeship on Old Earth. Here she has gained access to an information matrix created by the Others--the same mysterious Others who moved Old Earth to save it from the Core. But who are these Others? What has Aenea learned from them? And why has Old Earth been turned into a stage upon which cybrids from the past--from John Keats to Frank Lloyd Wright--repeat historical dramas of human genius for purposes known only to the Others?

The answers to these questions must wait. Together with the android A. Bettik, Endymion and his beloved Aenea embark on a final mission to find and comprehend the underlying fabric of the universe. The surprising nature of this medium and Aenea's ability to instruct her growing army of disciples in its discovery and use could provide the one weapon powerful enough to thwart their enemies while liberating humanity. Meanwhile, the enigmatic Shrike--monster, angel, killing machine--has followed them on their intergalactic sojourn and now stands ready to complete its own mission, revealing at last the long-held secret of its origin and purpose.

In The Rise of Endymion, Dan Simmons masterfully weaves together the complex strands of this extraordinary series. He answers all of the unsolved mysteries posed in the earlier volumes and brings the story full circle to the planet Hyperion, where it all began. A work of unparalleled power and vision, The Rise of Endymion is a masterpiece of the imagination by one of our most gifted writers.

Spin Trilogy: Book 2

Chris Moriarty

Call Arkady a clone with a conscience. Or call him a traitor. A member of the space-faring Syndicates, Arkady has defected to Israel with a hot commodity: a genetic weapon powerful enough to wipe out humanity. But Israel’s not buying it. They’re selling it–and Arkady–to the highest bidder.

As the auction heats up, the Artificial Life Emancipation Front sends in Major Catherine Li. Drummed out of the Peacekeepers for executing Syndicate prisoners, Li has now literally hooked up with an AI who has lived many lifetimes and shunted through many bodies. But while they have their own conflicting loyalties to contend with, together they’re just one player in a mysterious high-stakes game....

The Invincible

Ace SF Special, Series 2: Book 4

Stanislaw Lem

An interstellar 2nd-class cruiser called Invincible, lands on Regis III which seems bleakly uninhabited, to investigate the loss of sister ship, Condor. The crew finds evidence of a form of quasilife, born thru evolution of autonomous, self-replicating machines. The evolution was controlled by robot wars. The survivors are swarms of minuscule, insectoid machines. Individually or in small groups they're harmless & capable of only simple behavior. However, when bothered, they form huge swarms displaying complex behavior arising from self-organization & are able to defeat an intruder by a powerful surge of EMI. Some members of the crew suffer complete memory erasure as a consequence. Big clouds are also capable of high speed travel to the troposphere. The angered crew attempts to fight the enemy, but eventually recognize the meaninglessness of their efforts in the most direct sense of the word.

The novel turns into an analysis of the relationship between different life domains & their place in the cosmos. It's a thought experiment demonstrating that evolution may not necessarily lead to dominance by intellectually superior life forms. The plot also involves a Conrad-like dilemma, juxtaposing human values & the efficiency of mechanical insects.

Spin State

Spin Trilogy: Book 1

Chris Moriarty

UN Peacekeeper Major Catherine Li has made thirty-seven faster-than-light jumps in her lifetime - and has probably forgotten more than most people remember. But that's what backup hard drives are for. And Li should know; she's been hacking her memory for fifteen years in order to pass as human. But no memory upgrade can prepare Li for what she finds on Compson's World: a mining colony she once called home and to which she is sent after a botched raid puts her on the bad side of the powers that be. A dead physicist who just happens to be her cloned twin. A missing dataset that could change the interstellar balance of power and turn a cold war hot. And a mining "accident" that is starting to look more and more like murder...

Suddenly Li is chasing a killer in an alien world miles underground where everyone has a secret. And one wrong turn in streamspace, one misstep in the dark alleys of blackmarket tech and interstellar espionage, one risky hookup with an AI could literally blow her mind.

Olympos

The Ilium / Olympos Duology: Book 2

Dan Simmons

Beneath the gaze of the gods, the mighty armies of Greece and Troy met in fierce and glorious combat, scrupulously following the text set forth in Homer's timeless narrative. But that was before one observer -- Twenty-first Century scholar Thomas Hockenberry -- stirred the bloody brew; before an enraged Achilles joined forces with his archenemy Hector; and before the fleet-footed mankiller turned his murderous wrath on Zeus, Hera, Athena, Aphrodite, Apollo, and the entire pantheon of divine manipulators.

Now, all bets are off.

The Peace War

Across Realtime: Book 1

Vernor Vinge

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.

The Trials

The Red: Book 2

Linda Nagata

In the wake of nuclear terrorism, a squad of elite soldiers must combat artificial intelligence and seek justice in this military political thriller, a sequel to The Red: First Light.

Lieutenant James Shelley and his squad of US Army soldiers were on a quest for justice when they carried out the unauthorized mission known as First Light. They returned home to America to face a court-martial, determined to expose the corruption in the chain of command that compelled their actions. But in a country still reeling from the nuclear terrorism of Coma Day, the courtroom is just one battlefield of many.

A new cycle of violence ignites when rumors of the elusive, rogue AI known as the Red go public - and Shelley is, once again, pulled into the fray. Challenged by his enemies, driven by ideals, Shelley feels compelled to act. But are the harrowing choices he makes really his own, or are they made for him, by the Red? And with millions of lives at stake in a game of nuclear cat-and-mouse, does the answer even matter?

Raft

The Xeelee Sequence: Book 1

Stephen Baxter

Stephen Baxter's highly acclaimed first novel and the beginning of his stunning Xeelee Sequence. A spaceship from Earth accidentally crossed through a hole in space-time to a universe where the force of gravity is one billion times as strong as the gravity we know. Somehow the crew survived, aided by the fact that they emerged into a cloud of gas surrounding a black hole, which provided a breathable atmosphere. Five hundred years later, their descendants still struggle for existence, divided into two main groups. The Miners live on the Belt, a ramshackle ring of dwellings orbiting the core of a dead star, which they excavate for raw materials. These can be traded for food from the Raft, a structure built from the wreckage of the ship, on which a small group of scientists preserve the ancient knowledge which makes survival possible. Rees is a Miner whose curiosity about his world makes him stow away on a flying tree -- just one of the many strange local lifeforms -- carrying trade between the Belt and the Raft.

Accepted as an apprentice scientist, he learns that their world is dying, and that in order to live these survivors must contemplate a journey even more perilous and fantastic than that of their ancestors.

Going Dark

The Red: Book 3

Linda Nagata

In the third book in The Red Trilogy, former Army Lt. James Shelley becomes a black ops sniper working for the Red--a suspected rogue artificial intelligence that is ripped from today's headlines.

James Shelley has left his lover, Delphi, and his companion-in-arms, Jayne Vasquez, with a fortune acquired from a fallen oligarch. They believe him to be dead, and he doesn't try to set the record straight. His long-running question has been answered: There are other soldiers like him who have served the purposes of the Red--and he has accepted his place among them. As a soldier of the Red he pursues covert missions designed to nudge history away from existential threats--but that doesn't mean the world is growing more orderly. It's only in the froth of a "managed chaos" that human potential can grow and thrive. Shelley's missions eventually take him into orbit--and into conflict with those he loves--Delphi and Jaynie--who are determined to escape the influence of the Red.

Maelstrom

Rifters: Book 2

Peter Watts

This is the way the world ends:

A nuclear strike on a deep sea vent. The target was an ancient microbe-voracious enough to drive the whole biosphere to extinction-and a handful of amphibious humans called rifters who'd inadvertently released it from three billion years of solitary confinement.

The resulting tsunami killed millions. It's not as through there was a choice: saving the world excuses almost any degree of collateral damage.

Unless, of course, you miss the target.

Now North America's west coast lies in ruins. Millions of refugees rally around a mythical figure mysteriously risen from the deep sea. A world already wobbling towards collapse barely notices the spread of one more blight along its shores. And buried in the seething fast-forward jungle that use to be called Internet, something vast and inhuman reaches out to a woman with empty white eyes and machinery in her chest. A woman driven by rage, and incubating Armageddon.

Her name is Lenie Clarke. She's a rifter. She's not nearly as dead as everyone thinks.

And the whole damn world is collateral damage as far as she's concerned....

Fool's War

Sarah Zettel

For 500 years we have carried our ancient hatreds and millennia-old wars into interstellar space. With them have gone the seeds of new self-aware lifeforms mutating from artificial intelligences, technoviruses, and info-flow. Beings with no bodies and no limits, evolving to leap from cyberspace to outer space. Beings born to be our rivals...

Katmer Al Shei, owner of the starship Pasadena, does not know she is carrying a live entity in her ship's computer systems. Or that the electronic network her family helped weave holds a new race fighting for survival. Or that her ship's professional Fool is trying to avert a battle that could destroy entire worlds. And when Al Shei learns the truth, all she'll really know is that it's time to take sides...

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.

Colossus

Colossus: Book 1

D. F. Jones

Charles Forbin has dedicated the last ten years of his life to the construction of his own supercomputer, Colossus, rejecting romantic and social endeavours in order to create the United States' very first Artificially Intelligent defence system.

Colossus is a supercomputer capable of in-taking and analyzing data rapidly, allowing it to make real time decisions about the nation's defense.

But Colossus soon exceeds even Forbin's calculated expectations, learning to think independently of the Colossus Programming Office, processing data over one hundred times faster than Forbin and his team had originally anticipated.

The President hands off full control of the nation's missiles and other defense protocols to Colossus and makes the announcement to the world that he has ensured peace.

However, the USSR quickly announces that it too has a supercomputer, Guardian, with capabilities similar to that of Colossus.

Forbin is concerned when Colossus asks--asks--to communicate with Guardian. The computer he built shouldn't be able to ask at all...

Colossus and Guardian begin to communicate, quickly bypassing existing knowledge ... and the parameters placed on them by their creators. They are perfectly smart and totally in control. However, they lack human empathy and emotion, creating horrific scenarios.

Colossus and its Russian counterpart, Guardian, soon compromise US military secrecy, ultimately subjugating their creators with the threat of nuclear war.

And while Colossus has been specifically designed not to understand emotion - so as to make quicker and more logical decisions about America's safety - this is exactly the thing that makes him so lethal; Colossus does not experience human empathy and is incapable of understanding the moral ramifications of his decisions.

Having handed over total control of American defence missiles to Colossus, the President and Forbin must act quickly to shut down the unstable machine.

Will Forbin be able to take down the machine he's spent ten years building?

Will Colossus cause real damage before it's too late?

Find out in D.F. Jones's thrilling novel Colossus, which deals with the ongoing battle - both physical and philosophical - between man and machine, addresses the author's own apprehensive attitude towards our future. His message is still as poignant and moving today and when the novel was originally published in 1966.

The Garden of Rama

Rama Series: Book 3

Arthur C. Clarke
Gentry Lee

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.

Poseidon's Wake

Poseidon's Children: Book 3

Alastair Reynolds

Two hundred years after the fall of Mechanism, human society has achieved a kind of stability. There are colonies beneath the oceans, throughout the solar system, and beyond: on the worlds of extrasolar systems. Vast hemirelativistic ships connect these colonies, travelling at half the speed of light. Or rather they would, if the ominous presence of the alien Watchkeepers had not led to an enforced moratorium on interstellar travel.

But when a seemingly impossible radio signal reaches the colony Crucible, everything changes:

Send Ndege

Its origin is unpopulated, unexplored space. No one could be there at least, not if they travelled using human technology so who could have sent it? How did they get there? And what use do they have for the disgraced scientist Ndege Akinya?

Finding the answers will require one of the greatest expeditions humankind has ever launched, a journey further than ever attempted before, conducted under the implacable scrutiny of the Watchkeepers.

But as a mission is prepared on Crucible, it turns out they werent the only ones to see the message or its potential...

Elizabeth Bear

On a broken ship orbiting a doomed sun, dwellers have grown complacent with their aging metal world. But when a serving girl frees a captive noblewoman, the old order is about to change....

Ariane, Princess of the House of Rule, was known to be fiercely cold-blooded. But severing an angel's wings on the battlefield-even after she had surrendered-proved her completely without honor. Captive, the angel Perceval waits for Ariane not only to finish her off-but to devour her very memories and mind. Surely her gruesome death will cause war between the houses-exactly as Ariane desires. But Ariane's plan may yet be opposed, for Perceval at once recognizes the young servant charged with her care.

But it is a perilous journey through the crumbling hulk of a dying ship, and they do not pass unnoticed. Because at the hub of their turning world waits Jacob Dust, all that remains of God, following the vapor wisp of the angel. And he knows they will meet very soon.

The Centauri Device

M. John Harrison

John Truck was to outward appearances just another lowlife spaceship captain. But he was also the last of the Centaurans - or at least, half of him was - which meant that he was the only person who could operate the Centauri Device, a sentient bomb which might hold the key to settling a vicious space war.

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.
