On a far future Earth, mankind's achievements are immense: artificially intelligent robots, genetically uplifted animals, interplanetary travel, genetic modification of the human form itself. But nothing comes without a cost. Humanity is tired, its vigour all but gone. Society is breaking down into smaller communities, dispersing into the countryside and abandoning the great cities of the world. As the human race dwindles and declines, which of its great creations will inherit the Earth? And which will claim the stars?

After two decades in space, a man returns to Earth as something new and not completely human, in this "enormously inventive" novel by a Nebula Award winner (Galaxy Science Fiction). Twenty years ago, Asher Sutton vanished somewhere in the star system 61 Cygni, an inaccessible corner of the universe that humankind has thus far been unable to explore. Now Asher has returned to Earth, having impossibly survived catastrophic damage to his spacecraft. But the star-traveler is not the same man he was when he began his journey two decades earlier. He is, in fact, no longer completely human. And he is not alone. But he has a message to convey that could have reality-altering consequences for the human galaxy-conquerors who consider themselves almost gods, and for the nearly human androids they create, enslave, and oppress. It is Asher's destiny to change everything. His mission has made him a hero to some, a pariah to others--and a target for determined time-traveling assassins from the future whose mission it is to silence him at all costs before everything they cherish is obliterated. A true science fiction visionary, SFWA Grand Master Clifford D. Simak infused thrilling stories of time travel, space exploration, artificial intelligence, and alien contact with powerful, thought-provoking ideas. An enthralling masterwork of speculative fiction that astonishes while exploring humanity in all its disparate aspects, Time and Again can be counted among the prolific, multiple Hugo and Nebula Award-winning author's most brilliantly imagined and successfully realized creations.

His body hosting a pair of strange alien presences, an amnesiac space traveler returns home to an unrecognizable Earth Many centuries in the future, a two-hundred-year-old man is discovered hibernating in a space capsule orbiting a distant star. Transported back to his home planet, Andrew Blake awakens to an Earth he does not recognize--a world of flying cars and sentient floating houses--with no memory whatsoever of his history or purpose. But he has not returned alone. The last survivor of a radical experiment abandoned more than a century earlier, Blake was genetically altered to be able to adapt to extreme alien environments, and now he can sense other presences inhabiting his mind and body. One is a biological computer of astonishing power; the other is a powerful creature akin to a large wolf. And Blake is definitely not the one in control. With his sanity hanging in the balance, Blake's only option is to set out in frantic pursuit of his past, the truth, his destiny--and quite possibly the fate of humankind. A bravura demonstration of unparalleled imagination, intelligence, and heart, The Werewolf Principle addresses weighty issues of genetic manipulation that are as relevant today as when the novel first appeared in print. One of the all-time best and brightest in speculative fiction, Grand Master Clifford D. Simak offers a moving, stunning, witty, and thought-provoking exploration of what it means to be human.

Two present-day investigators race across time to escape malevolent aliens from the future and their terrible "gift" of immortality in this novel by a Nebula Award-winning author. What is the price of eternal life? Secret agent Jay Corcoran is about to learn the answer when his investigation into an inexplicable disappearance carries him and journalist friend Tom Boone hundreds of years into the past. Corcoran and Boone's powerful extrasensory abilities lead them to an advanced transportation system through time, and back to the bucolic eighteenth-century English countryside. There, they discover a family from the distant future hiding from the Immortals--an alien race that, many centuries on, is seducing human subjects with the promise of eternal life. But at the cost of the corporeal self, there is no place in the aliens' future for anyone unwilling to exist as mind alone. Now that the Evans family's sanctuary has been breached, escape is the only answer--for Boone and Corcoran as well--and the only way out is forward . . . far forward. But racing through space and time can be a hazardous occupation, especially with monstrous beasts, killer robots, and Immortal body-destroyers waiting at every juncture. The last novel from acclaimed science fiction Grand Master Clifford D. Simak, winner of the Hugo, Nebula, and numerous other awards, Highway of Eternity combines breathtaking action with provocative ideas and unparalleled ingenuity, the hallmarks of Simak's exceptional art. It is a fitting finale for the man who stands alongside Heinlein, Asimov, Bradbury, and Clarke as one of the true giants of speculative fiction's Golden Age.

From science fiction Grand Master Clifford D. Simak, an interstellar adventure of aliens, fairies, and time travel. Until the day he was murdered, Professor Peter Maxwell was a respected faculty member of the College of Supernatural Phenomena. Imagine his chagrin when he turns up at a Wisconsin matter transmission station several weeks later and discovers he's not only dead but unemployed. During an interstellar mission to investigate rumors of dragon activity, this alternate Maxwell was intercepted by a strange alien race that wanted him to carry knowledge of a remarkable technology back to Earth, and it seems someone does not want the information shared. Suddenly, it's essential for Maxwell to find his own killer. He enlists the aid of Carol Hampton of the Time College, along with her pet saber-tooth tiger, a ghost with memory issues, and the intelligent Neanderthal Man recently rescued from a prehistoric cooking pot. But the search is pointing them toward the goblins, fairies, and assorted Little Folk living in reservations on campus, and into the dangerous heart of an interspecies blood feud that has been raging for millions of years. Ingeniously inventive and unabashedly tongue-in-cheek, this novel demonstrates multi-award-winning fantasy and science fiction favorite Clifford D. Simak operating at the imaginative peak of his considerable powers.

Armchair Fiction presents extra large editions of classic science fiction double novels. The first novel is sci-fi maestro Murray Leinster's "The Wailing Asteroid." There was no life on the asteroid, but the miles of rock-hewn corridors through which the Earth party wandered left no doubt about the purpose of the asteroid. It was a mighty fortress, stocked with weapons of destruction beyond man's power to understand. And yet there was no life here, nor had there been for untold centuries. What race had built this stronghold? What unimaginable power were they defending against? Why was it abandoned? There was no answer, all was dead. But-not quite all. For in a room above the tomb-like fortress a powerful transmitter beamed its birdlike, fluting sounds toward Earth. Near it, on a huge star map of the universe, with light-years measured by inches, ten tiny red sparks were moving, crawling inexorably toward the center. Moving, at many times the speed of light, with the acquired mass of suns...moving, on a course that would pass through the solar system. The unknown aliens would not even see our sun explode from the force of their passing. They would not even notice the tiny speck called Earth as it died... The second novel is "The World that Couldn't Be" by one of the top-tier science fiction writers of all time, Clifford D. Simak. Life on the planet Laynard was more than unusual. Gavin Duncan had settled on this distant planet because it was virtually unspoiled and unpopulated by man, making the farming opportunities endless. While his livelihood depended on this plantation being a success, he did not know the planet well, or its peculiarities, and had virtually no knowledge about the wildlife. When he found he'd lost part of his crop to a strange beast, his job was plain... Like every farmer on every planet, Duncan had to hunt down anything that damaged his crop, and kill it. The natives were quite peculiar regarding the hunting of certain beasts, especially the one he was after, the Cytha. With a lot of persuasion, he finally sets out with a local native to track the beast. During the hunt, the strangest things began to take place, and Duncan gets a lesson the hard way about xeno-ecology
