Book
Imperial Earth
by Arthur C. Clarke
Editorial Reviews Product Description Imperial Earth is the fascinating odyssey of Duncan Makenzie, traveling from Titan, a moon of Saturn, to Earth, as a diplomatic guest of the United States for the celebration of its Quincentennial in the year 2276. Titan, an independent republic, was originally colonized from Earth three generations earlier. Duncan's initial challenge is to prepare, physically and intellectually, for the 500-million-mile trip to Earth. Once there, he is caught up in a sweep of new experiences, including the social and political whirl in Washington, a strange visit to a carefully preserved ancient city once prominent in the 20th century, and a search for and meeting with a woman he loved since she visited Titan years before. The result of twenty years of thought by a celebrated novelist and scientist, and overflowing with skilled characterization and exciting events, Imperial Earth is one of Arthur C. Clarke's most ambitious, successful, and important novels.




Book
Iron Sunrise
by Charles Stross
“[Stross] has the ability to superimpose an intriguing take on contemporary events over an imaginative story peopled by bizarre characters.” – The Kansas City Star A G2 star doesn’t just explode—not without outside interference. So the survivors of the planet Moscow, which was annihilated in just such an event, have launched a counterattack 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. Opposing her is an unknown—and unimaginable—enemy. At stake is not only the fate of New Dresden but also the very order of the universe. And the one person who knows the identity of that enemy is a disaffected teenager who calls herself Wednesday Shadowmist. But Wednesday has no idea what she knows…



Book
Exultant
by Stephen Baxter
“Baxter has an uncanny gift for mixing a punchy, cyberpunk cynicism with his resolutely hard SF story base. . . . [Exultant] rivals Asimov in its boundless vision for the future evolution of humanity.”—Kirkus Reviews (starred review) For more than twenty thousand years, humans have been at war with the alien race of Xeelee. Faced with certain death, a young pilot, Pirius, disobeys orders and travels into the future. Upon his return, Pirius is court-martialed and sentenced to penal servitude. But it is not only Pirius who pays the price. In flying into the future and back again, Pirius returned to a time before he’d left, a time inhabited by his younger self, who also receives punishment. Commissary Nilis believes that the elder Pirius, whom he dubs Pirius Blue, may know how to defeat the Xeelee. But Nilis can do nothing for Pirius Blue. Instead, he takes the younger Pirius—Pirius Red—back to Earth. There Pirius Red will discover truths that shatter his preconceived notions of all that he is fighting for, while Pirius Blue will learn even harsher truths. But the most shocking revelation of all is still to come. “Absurdly ambitious, technically brilliant, and downright exciting.”—SFX Magazine “Striking . . . chilling . . . [with] a triumphant conclusion.”—Starburst

Book
Accelerando
by Charles Stross
The Singularity. It is the era of the posthuman. Artificial intelligences have surpassed the limits of human intellect. Biotechnological beings have rendered people all but extinct. Molecular nanotechnology runs rampant, replicating and reprogramming at will. Contact with extraterrestrial life grows more imminent with each new day. Struggling to survive and thrive in this accelerated world are three generations of the Macx clan: Manfred, an entrepreneur dealing in intelligence amplification technology whose mind is divided between his physical environment and the Internet; his daughter, Amber, on the run from her domineering mother, seeking her fortune in the outer system as an indentured astronaut; and Sirhan, Amber’s son, who finds his destiny linked to the fate of all of humanity. For something is systematically dismantling the nine planets of the solar system. Something beyond human comprehension. Something that has no use for biological life in any form...

Book
Deepsix

But catastrophe awaits when they are stranded on this strange and complex world of puzzles and impossibilities. And now Hutch and her people must somehow survive on a hostile world going rapidly mad -- as the clock ticks toward apocalypse for a doomed enigma now called...

Book
Blindsight
by 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...

Book
The Algebraist
by Iain M. Banks
“Banks is a phenomenon…Wildly successful, fearlessly creative.”—William Gibson, author of Neuromancer, winner of the Hugo, Nebula, and Philip K. Dick Awards It is 4034 AD. Humanity has made it to the stars. Fassin Taak, a Slow Seer at the Court of the Nasqueron Dwellers, will be fortunate if he makes it to the end of the year. The Nasqueron Dwellers inhabit a gas giant on the outskirts of the galaxy, in a system awaiting its wormhole connection to the rest of civilization. In the meantime, they are dismissed as decadents living in a state of highly developed barbarism, hoarding data without order, hunting their own young and fighting pointless formal wars. Seconded to a military-religious order he's barely heard of — part of the baroque hierarchy of the Mercatoria, the latest galactic hegemony — Fassin Taak has to travel again amongst the Dwellers. He is in search of a secret hidden for half a billion years. But with each day that passes a war draws closer — a war that threatens to overwhelm everything and everyone he's ever known.
