    So enter it prepared! Here are vivid tales about possible tomorrows, from the keen eye and colorful pen of David Brin, a modern master of speculative fiction. Visit a chillingly plausible tomorrow, when prisoners may be sent to asteroidal gulags. Or might prisons vanish and felons roam, seeing only what society allows? Suppose, amid lavish success, we gain the superpower to fly! Will we even appreciate it or will we find new reasons to complain? In "Mars Opposition," you'll experience an alien invasion like no other, confronting humanity with a stark and terrible choice followed by several more tales of conquest from beyond, each of them wildly different.

And Reality Check asks one of you readers just one of you to wake up! Tomorrow awaits. We can face it and prevail. So long as our stance is brave INSISTENCE OF VISION."

    S. Lewis’s adult religious books, a repackaged edition of the revered author’s definitive collection of short fiction, which explores enduring spiritual and science fiction themes such as space, time, reality, fantasy, God, and the fate of humankind.From C.S. Lewis—the great British writer, scholar, lay theologian, broadcaster, Christian apologist, and author of Mere Christianity, The Screwtape Letters, The Great Divorce, The Chronicles of Narnia, and many other beloved classics—comes a collection of his dazzling short fiction.This collection of futuristic fiction includes a breathtaking science fiction story written early in his career in which Cambridge intellectuals witness the breach of space-time through a chronoscope—a telescope that looks not just into another world, but into another time. As powerful, inventive, and profound as his theological and philosophical works, The Dark Tower reveals another side of Lewis’s creative mind and his longtime fascination with reality and spirituality. It is ideal reading for fans of J. R. R. Tolkien, Lewis’s longtime friend and colleague.

    (David) Marusek . . . may have a relatively modest body of work (just ten short stories in print over the span of 13 years), but each of these pieces has so far proven to be as concentrated and potent as a dwarf star.S--Dave Itzkoff, The New York Times

    The novella “A Necessary Being” showcases Octavia E. Butler’s ability to create alien yet fully believable “others.” Tahneh’s father was a Hao, one of a dwindling race whose leadership abilities render them so valuable that their members are captured and forced to govern. When her father dies, Tahneh steps into his place, both chief and prisoner, and for twenty years has ruled without ever meeting another of her kind. She bears her loneliness privately until the day that a Hao youth is spotted wandering into her territory. As her warriors sharpen their weapons, Tahneh must choose between imprisoning the newcomer—and living the rest of her life alone. The second story in this volume, “Childfinder,” was commissioned by Harlan Ellison for his legendary (and never-published) anthology The Last Dangerous Visions™. A disaffected telepath connects with a young girl in a desperate attempt to help her harness her growing powers. But in the richly evocative fiction of Octavia E. Butler, mentorship is a rocky path, and every lesson comes at a price. The award-winning author of science fiction classics Parable of the Sower and Kindred bestows these compelling, long lost gems “like the miraculous discovery that the beloved book you’ve read a dozen times has an extra chapter” (Los Angeles Review of Books).

    Named after the migrant workers of America's Dust Bowl, these novels convey Blish's "history of the future," a brilliant and bleak look at a world where cities roam the Galaxy looking for work and a sustainable way of life.In the first novel, They Shall Have Stars, man has thoroughly explored the Solar System, yet the dream of going even further seems to have died in all but one man. His battle to realize his dream results in two momentous discoveries anti-gravity and the secret of immortality. In A Life for the Stars, it is centuries later and anti-gravity generations have enabled whole cities to lift off the surface of the earth to become galactic wanderers. In Earthman, Come Home, the nomadic cities revert to barbarism and marauding rogue cities begin to pose a threat to all civilized worlds. In the final novel, The Triumph of Time, history repeats itself as the cities once again journey back in to space making a terrifying discovery which could destroy the entire Universe. A serious and haunting vision of our world and its limits, Cities in Flight marks the return to print of one of science fiction's most inimitable writers.A Selection of the Science Fiction Book Club

    The People escaped the destruction of their home planet and crashed on Earth in the Southwest just before the turn of the century. Fully human in appearance, they possessed many extraordinary powers. Henderson's People stories tell of their struggles to fit in and to live their lives as ordinary people, unmolested by fearful and ignorant neighbors. The People are "us at our best, as we hope to be, and where (with work and with luck) we may be in some future."Ingathering contains all seventeen of the People stories, including one, "Michal Without," which has never before been published.
