Now, as faster-than-light drive opens the stars to exploration, humans are finding other relics of the race they call the Monument-Makers - each different, and each heartbreakingly beautiful. But except for a set of footprints on Jupiter's moon Iapetus, there is no trace of the enigmatic race that has left them behind. Then a team of scientists working on a dead world discover an ominous new image of the Monument-Makers. Somehow it all fits with other lost civilizations, and possibly with Earth's own future. And distant past. But Earth itself is on the brink of ecological disaster - there is no time to search for answers. Even to a question that may hold the key to survival for the entire human race...

    David Grinspoon, a planetary scientist who has helped to shape modern planetary exploration, brings the subject to a new generation of readers with his reflections on the most recent developments in astrobiology, including NASA's search for life on Mars. In Lonely Planets, he investigates the big questions: How widespread are life and intelligence in the cosmos? Is life on Earth an accident or in some sense the "purpose" of this universe? And how can we, working from the Earth-centric definition of "life," even begin to think about the varieties of life-forms on other planets?Using the topic of extraterrestrial life as a mirror with which to view human beliefs, evolution, history, and aspirations, Grinspoon provides an authoritative scientific narrative of cosmic evolution, along with provocative ruminations on how we fit into the story of the universe. An accessible, lively blend of science, history, philosophy, and personal narrative, Lonely Planets reveals how the search for extraterrestrial life unites our spiritual and scientific quests for connection with the cosmos.

    It is the moment when the universe suffers a crisis of conscience. Should it expand or make a great big bang? It decides to wind the clock back a decade to 1991, making everyone in the world endure ten years of deja-vu and a total loss of free will - not to mention the torture of reliving every nanosecond of one of the tawdiest and most hollow decades. With his trademark wicked wit, Vonnegut addresses memory, suicide, the Great Depression, the loss of American eloquence, and the obsolescent thrill of reading books.

    Some stories have won awards; some have been included in various 'Year's Best' anthologies; some have been well reviewed by critics and readers; and some are simply Ken's personal favorites. Many of the authors collected here (with the obvious exception of Liu Cixin) belong to the younger generation of 'rising stars'.In addition, three essays at the end of the book explore Chinese science fiction. Liu Cixin's essay, The Worst of All Possible Universes and The Best of All Possible Earths, gives a historical overview of SF in China and situates his own rise to prominence as the premier Chinese author within that context. Chen Qiufan's The Torn Generation gives the view of a younger generation of authors trying to come to terms with the tumultuous transformations around them. Finally, Xia Jia, who holds the first Ph.D. issued for the study of Chinese SF, asks What Makes Chinese Science Fiction Chinese?.

    John Harrison’s dangerously illuminating new novel, three quantum outlaws face a universe of their own creation, a universe where you make up the rules as you go along and break them just as fast, where there’s only one thing more mysterious than darkness.In contemporary London, Michael Kearney is a serial killer on the run from the entity that drives him to kill. He is seeking escape in a future that doesn’t yet exist—a quantum world that he and his physicist partner hope to access through a breach of time and space itself. In this future, Seria Mau Genlicher has already sacrificed her body to merge into the systems of her starship, the White Cat. But the “inhuman” K-ship captain has gone rogue, pirating the galaxy while playing cat and mouse with the authorities who made her what she is. In this future, Ed Chianese, a drifter and adventurer, has ridden dynaflow ships, run old alien mazes, surfed stellar envelopes. He “went deep”—and lived to tell about it. Once crazy for life, he’s now just a twink on New Venusport, addicted to the bizarre alternate realities found in the tanks—and in debt to all the wrong people.Haunting them all through this maze of menace and mystery is the shadowy presence of the Shrander—and three enigmatic clues left on the barren surface of an asteroid under an ocean of light known as the Kefahuchi Tract: a deserted spaceship, a pair of bone dice, and a human skeleton.

Included are major works from genre progenitors like Jack Williamson and Leigh Brackett, stylish midcentury voices like Cordwainer Smith and Samuel R. Delany, popular favorites like David Drake, Lois McMaster Bujold, and Ursula K. Le Guin, and modern-day pioneers such as Iain M. Banks, Steven Baxter, Scott Westerfeld, and Charles Stross.

    Here the German-born scientist Wernher von Braun detailed what he believed were the problems and possibilities inherent in a projected expedition to Mars.    Today von Braun is recognized as the person most responsible for laying the groundwork for public acceptance of America's space program. When President Bush directed NASA in 1989 to prepare plans for an orbiting space station, lunar research bases, and human exploration of Mars, he was largely echoing what von Braun proposed in The Mars Project.

    The Wersgorix, whose scouting ship it is, are quite expert at taking over planets, and having determined from orbit that this one was suitable, they initiate standard world-conquering procedure. Ah, but this time it's no mere primitives the Wersgorix seek to enslave; they've launched their invasion against free Englishmen! In the end, only one alien is left alive; and Sir Roger's grand vision is born. He intends for the creature to fly the ship first to France to aid his King, then on to the Holy Land to vanquish the infidel.

But that knavish alien little understands the indomitable will and clever resourcefulness of Englishmen, no matter how great the odds against them. . .

    His only companions are the disembodied voice of Miranda Taligent, the only woman he has ever loved, and the cryogenically frozen body of her father Prospero, the genius and industrial magnate who drove her insane.The tale of Harold’s life is also one of an alternate reality, a lucid waking dream in which the well-heeled have mechanical men for servants, where the realms of fairy tales can be built from scratch, where replicas of deserted islands exist within skyscrapers.. As Harold’s childhood infatuation with Miranda changes over twenty years to love and then to obsession, the visionary inventions of her father also change Harold’s entire world, transforming it from a place of music and miracles to one of machines and noise. And as Harold heads toward a last desperate confrontation with Prospero to save Miranda’s life, he finds himself an unwitting participant in the creation of the greatest invention of them all: the perpetual motion machine.Beautifully written, stunningly imagined, and wickedly funny, The Dream of Perpetual Motion is a heartfelt meditation on the place of love in a world dominated by technology.

    The plan is to beat the Chinese to Mars--in under four days at three million miles an hour. It would be history in the making if it didn't sound so insane.

    Out pops a six-legged, two-armed alien, who says, in perfect English, "Take me to a paleontologist."It seems that Earth, and the alien's home planet, and the home planet of another alien species traveling on the alien mother ship, all experienced the same five cataclysmic events at about the same time, including events exactly like the meteor that wiped out the dinosaurs. Both alien races believe this proves the existence of God: i.e. he's obviously been manipulating the evolution of life on each of these planets.
