Moonseed
by Stephen Baxter
It Eats Planets. And It's Here. It starts when Venus explodes into a brilliant cloud of dust and debris, showering Earth with radiation and bizarre particles that wipe out all the crops and half the life in the oceans, and fry the ozone layer. Days later, a few specks of moon rock kicked up from the last Apollo mission fall upon a lava crag in Scotland. That's all it takes . . . Suddenly, the ground itself begins melting into pools of dust that grow larger every day. For what has demolished Venus, and now threatens Earth itself, is part machine, part life-form: a nano-virus, dubbed Moonseed, that attacks planets. Four scientists are all that stand between Moonseed and Earth's extinction, four brilliant minds that must race to cut off the virus and save what's left of Earth--a pulse-stopping battle for discovery that will lead them from the Earth's inner core to a daredevil Moon voyage that could save, or damn, us all.

Vacuum Diagrams
by Stephen Baxter
"And everywhere the Humans went, they found life ..." This dazzling future history, winner of the 2000 Philip K. Dick Award, is the most ambitious and exciting since Asimov's classic Foundation saga. It tells the story of Humankind -- all the way to the end of the Universe itself. Here, in luminous and vivid narratives spanning five million years, are the first Poole wormholes spanning the solar system; the conquest of Human planets by Squeem; GUTships that outrace light; the back-time invasion of the Qax: the mystery and legacy of the Xeelee, and their artifacts as large as small galaxies; photino birds and Dark Matter; and the Ring, where Ghost, Human, and Xeelee contemplate the awesome end of Time. Stephen Baxter is the most acclaimed and accomplished of a brilliant new generation of authors who are expanding the vision of science fiction and taking itto a new golden age.

But in seeking the secret of the lost sun, Byr risks losing himself. There is only one way to break the silence of millennia: steal the soul of the long-dead starship captain who first encountered the star, and convince her to be reborn.

Childhood's End
by Arthur C. Clarke
The inspiration for the Syfy miniseries. Childhoodâs End is one of the defining legacies of Arthur C. Clarke, the author of 2001: A Space Odyssey and many other groundbreaking works. Since its publication in 1953, this prescient novel about first contact gone wrong has come to be regarded not only as a science fiction classic but as a literary thriller of the highest order. Spaceships have suddenly appeared in the skies above every city on the planet. Inside is an intellectually, technologically, and militarily superior alien race known as the Overlords. At first, their demands seem benevolent: unify Earth, eliminate poverty, end war. But at what cost? To those who resist, itâs clear that the Overlords have an agenda of their own. Has their arrival marked the end of humankind . . . or the beginning? Praise for Childhoodâs End âA first-rate tour de force.ââThe New York Times âFrighteningly logical, believable, and grimly prophetic . . . Clarke is a master.ââLos Angeles Times âThere has been nothing like it for years; partly for the actual invention, but partly because here we meet a modern author who understands that there may be things that have a higher claim on humanity than its own âsurvival.â ââC. S. Lewis âAs a science fiction writer, Clarke has all the essentials.ââJeremy Bernstein, The New Yorker
Book
Sun of Suns
by Karl Schroeder
It is the distant future. The world known as Virga is a fullerene balloon three thousand kilometers in diameter, filled with air, water, and aimlessly floating chunks of rock. The humans who live in this vast environment must build their own fusion suns and "towns" that are in the shape of enormous wood and rope wheels that are spun for gravity. Young, fit, bitter, and friendless, Hayden Griffin is a very dangerous man. He's come to the city of Rush in the nation of Slipstream with one thing in mind: to take murderous revenge for the deaths of his parents six years ago. His target is Admiral Chaison Fanning, head of the fleet of Slipstream, which conquered Hayden's nation of Aerie years ago. And the fact that Hayden's spent his adolescence living with pirates doesn't bode well for Fanning's chances.

A stunning tour de force filled with transcendent awe and wonder, Hyperion is a masterwork of science fiction that resonates with excitement and invention, the first volume in a remarkable epic by the multiple-award-winning author of The Hollow Man. On the world called Hyperion, beyond the reach of galactic law, waits a creature called the Shrike. There are those who worship it. There are those who fear it. And there are those who have vowed to destroy it. In the Valley of the Time Tombs, where huge, brooding structures move backward through time, the Shrike waits for them all. On the eve of Armageddon, with the entire galaxy at war, seven pilgrims set forth on a final voyage to Hyperion seeking the answers to the unsolved riddles of their lives. Each carries a desperate hopeâand a terrible secret. And one may hold the fate of humanity in his hands. Praise for Dan Simmons and Hyperion âDan Simmons has brilliantly conceptualized a future 700 years distant. In sheer scope and complexity it matches, and perhaps even surpasses, those of Isaac Asimov and James Blish.ââThe Washington Post Book World âAn unfailingly inventive narrative . . . generously conceived and stylistically sure-handed.ââThe New York Times Book Review âSimmonsâs own genius transforms space opera into a new kind of poetry.ââThe Denver Post âAn essential part of any science fiction collection.ââBooklist

2010: Odyssey Two

Meanwhile, the being that was once Dave Bowmanâthe only human to unlock the mystery of the monolithâstreaks toward Earth on a vital mission of its own . . . âClarke deftly blends discovery, philosophy, and a newly acquired sense of play.ââTime â2010 is easily Clarkeâs best book in over a decade.ââThe San Diego Tribune
