Robot believers at the far end of the galaxy endeavor to create a true religion, but their efforts could be shattered by a shocking revelation. Far in the future, on the remote planet End of Nothing, sentient robots are engaged in a remarkable enterprise. They call their project Vatican-17: an endeavor to create a truly universal religion presided over by a pope, whose extreme godliness and infallible artificial intelligence are fed by telepathic human Listeners who psychically delve into the mysteries of the universe. But the great and holy mission could be compromised by one shocking revelation that threatens to inspire serious crises of faith among the spiritual, truth-seeking robotic acolytes while tearing them into warring religious factions; for the Listener Mary is claiming that she has just discovered Heaven. There are those among the Clifford D. Simak faithful who consider Project Pope his masterpiece. But whether the crowning literary achievement of a multiple Hugo and Nebula Award-winning science-fiction Grand Master or merely another brilliant novel of speculative fiction to stand among his many, Simak's breathtaking search for God in the machine ingeniously blends science and spirituality in a truly miraculous way that few science fiction writers, if any, have been able to accomplish.

A handful of humans and a multitude of robots create a new society on a mysteriously abandoned Earth in this breathtaking science fiction classic from one of the genre's acknowledged masters. What if you woke up one morning on Earth...and no one else was there? That is the reality that greeted a handful of humans, including Jason Whitney, his wife Martha, and the remnants of a tribe of Native Americans in the year 2135. Their inexplicable abandonment had unexpected benefits: the eventual development of mental telepathy and other extrasensory powers, inner peace, and, best of all, near immortality. Now, 5,000 years later, most of the remaining humans live a tranquil, pastoral life, leaving technological and religious exploration to the masses of robot servants who no longer have humans to serve. But the unexpected reappearance of Jason's brother, who had teleported to the stars many years before, threatens to change everything yet again - for John Whitney is the bearer of startling information about where Earth's population went and why. And the most disturbing news of all: They may finally be coming home again. Nominated for the Hugo Award when it first appeared in print more than 40 years ago, Clifford D. Simak's brilliant and thought-provoking A Choice of Gods has lost nothing of its power to astonish and intrigue. A masterwork of speculative fiction, intelligent and ingenious, it is classic Simak, standing tall among the very best science fiction that has ever been written.

Following a conversation with a talking slot machine, Professor Edward Lansing finds himself mysteriously transported to a tavern on a long and empty road. It is immediately obvious to the educator that he is no longer on campus - or even Earth - and that he is not alone. Lansing's new companions - a female engineer, a military officer, a humorless priest, a poetess, and a robot named Jurgens - all hail from separate alternate realities and share Lansing's confusion. What is clear, however, is that they must continue down the road together, encountering a series of bizarre sights, dangerous obstacles, and perplexing puzzles along the way: an abandoned, decaying city; a set of doorways; a large blue cube; a tower that sings.

For those who fail, the alien trail will never be seen again. A provocative science fiction allegory, Special Deliverance is Hugo and Nebula Award winner Clifford D.

Space travel has been abandoned in the 22nd century.

Now he's a company pariah, forced to flee the safe confines of the Fishhook complex. But the world he escapes into is not a safe sanctuary.

More than a thousand years have passed since humankind intentionally destroyed its treacherous technology, choosing to revert back to a primitive tribal state. In this society the rusting brain cases of long-inert robots are considered trophies, and the scant knowledge that has survived is doled out to an inquisitive few in monasterylike "universities". It is at one such center of learning that young Tom Cushing first reads of the legendary "Place of Going to the Stars", rumored to exist on a high butte somewhere in the western part of the land. Driven by enthusiasm and an insatiable need to track the myth to its source, Tom sets out on an amazing trek across what was once called America, teaming up with a witch, the world's last remaining robot, and other odd companions. But all the astonishing discoveries and dangers they encounter along the way will pale before the revelations that await them at journey's end. Clifford D.

A human space traveler trapped on a remote planet must somehow unravel a confounding alien technology - or else surrender himself to a host of incomprehensible horrors. For thousands of years, Carter Horton has been traveling across the galaxy toward a distant world capable of supporting human life. At journey's end, awakened from his millennia-long sleep by a curiously adaptive android, he is informed that his crewmates have all perished due to a system malfunction. But worse is yet to come: Horton's sentient ship is refusing to return him to Earth, and a strangely cordial predator is waiting for him on the planet's surface. The repulsive creature, Carnivore, arrived here via a tunnel across the universe, as did his late companion - a human dubbing himself William Shakespeare - whom Carnivore just recently devoured.

In rural Wisconsin, wonder clashes dangerously with corporate greed when an alien visitor opens up a gateway through time into a breathtaking prehistoric lost world. On sabbatical from teaching at a small university, paleontologist Asa Steele is content to relax amid the pastoral splendor of his Wisconsin farm. That is until his dog starts bringing home unrecognizable artifacts and, strangest of all, fresh dinosaur bones. Since boyhood, Asa has heard the rumors of a UFO crash site nearby, and his encounter with a cat-faced alien life form proves the old story to be shockingly true. A gregarious immortal stranded on Earth for 50,000 years, Catface has the power to create portals in time, and now he has opened a gateway into a prehistoric world of wonder and beauty, a place Asa calls "Mastodonia".
