If they fail, the entire world will be doomed.

    A legend as old as the stars rules this constructed world; When the seventh seventh seventh human Heptarch is crowned, he will be the Kristos and will bring eternal salvation . . . or the destruction of the cosmos.Patience is the only daughter of the rightful Heptarch, but she, like her father before her, serves the usurper who has destroyed her family. For she has learned the true ruler's honor.Duty to one's race is more important than duty to one's self. But the time for prudence has passed, and that which has slept for ages has awakened. And Patience must journey to the heartsoul of this planet to confront her destiny . . . and her world's.

    Heinlein's longest and most ambitious work, it is the story of a man so in love with Life that he refused to stop living it; and so in love with Time that he became his own ancestor.

    Now, with the entire city corrupted -from the people to the very buildings they inhabit- only the most wretched sort of existence remains. For security operative Tanner Mirabel, it is the landscape of nightmares through which he searches for a low-life postmortal killer. But the stakes are raised when his search brings him face to face with a centuries-old atrocity that history would rather forget.

    He can con humans, aliens and any number of robots time after time. Jim is so slippery that all the inter-galactic cops can do is make him one of their own

    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 two thieves had themselves been robbed by two youths, who eyed each other suspiciously over the sprawled, senseless bodies. Fafhrd said: 'Our motives for being here seem identical.' 'Surely, they must be!' the Mouser answered curtly, fiercely eyeing his huge, potential foe.Fafhrd glanced down at the belts and money-pouches of the fallen thieves. Then he looked up at the Mouser with an honest, open, ingenuous smile. 'Sixty-sixty?' he suggested. Thus was born the most improbable relationship in the whole history of swords and sorceries.Contains:7 • Induction • [Fafhrd and the Gray Mouser] • (1957) • shortstory by Fritz Leiber11 • The Snow Women • [Fafhrd and the Gray Mouser] • (1970) • novella by Fritz Leiber91 • The Unholy Grail • [Fafhrd and the Gray Mouser] • (1962) • novelette by Fritz Leiber123 • Ill Met in Lankhmar • [Fafhrd and the Gray Mouser] • (1970) • novella by Fritz Leiber

    What is it? Who came there to build it?The secret lies, perhaps, in the chaotic decades of the Martian Revolution, in the lost memories of those who have lived for centuries.

    Did some cryptic patron race begin the job long ago, then abandon us? Or did we leap all by ourselves? That question burns, yet a greater mystery looms ahead, in the furnace of a star. Under the caverns of Mercury, Expedition Sundiver prepares for the most momentous voyage in our history – into the boiling inferno of the sun, seeking our destiny in the cosmic order of life.

    NASA, NATO, and the UN sent explorers to the asteroid's surface...and discovered marvels and mysteries to drive researchers mad.For the Stone was from space--but perhaps not our space; it came from the future-but perhaps not our future; and within the hollowed asteroid was Thistledown. The remains of a vanished civilization. A human--English, Russian, and Chinese-speaking--civilization. Seven vast chambers containing forests, lakes, rivers, hanging cities...And museums describing the Death; the catastrophic war that was about to occur; the horror and the long winter that would follow. But while scientists and politicians bickered about how to use the information to stop the Death, the Stone yielded a secret that made even Earth's survival pale into insignificance.
