The World Government calls upon him for aid in protecting an alien diplomat from a powerful and hostile member of his own species. Knowing both the importance of the task and his inability to handle it on his own, Singer goes to confront his greatest conquest with a strange bargain. A shape-shifting alien, the last of his species, sits in a special cage at an institute dedicated to the study of extraterrestrial beings. Most frequently he projects the aspect of a one-eyed catlike creature, but he can appear as almost anything.One of Singer’s secrets, and his greatest guilt, is his suspicion that the creature is intelligent. He confronts him and offers his own life for Cat’s cooperation in saving the alien. Cat accepts, and later, their mission fulfilled, demands a refinement on the original bargain. Rather than a simple death he wants a return bout—a chase with Singer as the hunted rather than the hunter.The gods, powers and monsters of Navajo legend provide the backdrop for the working out of Singer’s fate—for the chase is as much for his soul as for his body. As he uses matter transmitters to flit from Paris to London to the Middle East to the American Southwest, he must search back into his own early life as well as the root beliefs of his vanished people and come to terms with a world that has adopted him, made use of his skills, and left him feeling that he has no place to call his own.

    The title is a play on words, one meaning "the force which pulls" & the other being "extremely serious or important". It was serialized in Astounding Science Fiction, 4–7/53. Its 1st cloth publication was in '54. It was 1st published in paper in '58. Along with the novel itself, many editions (& most recent editions) of the book also include Whirligig World, an essay on creating the planet Mesklin that was published in the 6/53 Astounding. He published two sequels, a '70 novel called Star Light & a '73 short story called Lecture Demonstration. Mission of Gravity was nominated for a Retro Hugo Award for '54.For a profit & adventure Barlennan would sail thousands of miles across uncharted waters, into regions where gravity played strange tricks. He'd dare the perils of strange tribes & stranger creatures--even dicker with those aliens from beyond the skies, though the concept of another world was unknown to the inhabitants of the planet of Mesklin. But in spite of the incredible technology of the strangers & without regard for their enormous size, Barlennan had the notion of turning the deal to an unsuspected advantage for himself--a considerable enterprise for a being very much resembling a 15" caterpillar!

    Each section has a different atmosphere and habitat to cater for the many different species.. all the problems of the staff and patients are in this book.. how to design a spacesuit for a surgeon with eight legs?

    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.

    Naked-hided, blunt toothed and blunt-fingered, Tully was the sole surviving member of his company -- a communicative, spacefaring species hitherto unknown -- and he was a prisoner of his discoverer/ captors the sadistic, treacherous kif, until his escape onto the hani ship The Pride of Chanur. Little did he know when he threw himself upon the mercy of The Pride and her crew that he put the entire hani species in jeopardy and imperiled the peace of the Compact itself. For the information this fugitive held could be the ruin or glory of any of the species at Meetpoint Station. Cover art by Michael Whelan

    

    A time storm has devastated the Earth, and only a small fraction of humankind remains. From the rubble, three survivors form an unlikely alliance: a young man, a young woman, and a leopard.

    And suddenly uncertainty and change had come to the placid paradise that was Thalassa.

    He is an eternal warrior destined to combat the Dark Lord through all time for dominion of the Earth. Follow him, servant of a great race, as he battles his enemy down the halls of time, from the caves of our ancestors to the final confrontation under the hammer of nuclear annihilation.

    To these new worlds come the Immortals, beings with strange ties to ancient Earth who seem to live forever, who can travel light years in days -- and who use their strange powers to control the existence of ordinary mortals. On the planet Pentecost, a small group sets out to find and challenge the Immortals. But in the search they themselves are changed: as Immortals, they discover a new threat, not just to themselves, but to the galaxy itself.

    The invention of the Hotline -- a constant stream of data from a star in the constellation Ophiuchus -- facilitates survival and enables the development of amazing new technologies. Then, after 400 years, humanity's unknown helpers send a bill for their services...and suddenly everything is threatened once again.The Ophiuchi Hotline was John Varley's first novel, and it received nominations for both the Hugo and Nebula awards; he later won both for his book Persistence of Vision.

    A man without a planet, he gains immortality from an elixir drunk during a sexual interlude with a cat-like alien queen in heat. Now, with his pet owl, his dog Anubis and a sexy robot companion, Simon charts a 3,000-year course to the most distant corners of a multiverse full of surprises to seek out the answers to the questions no one can seem to answer.

    For although the UN has slated "anomalous" children for deportation and destruction, other people—especially Supreme Goodmember Arnie Kott of the Water Worker's union—suspect that Manfred's disorder may be a window into the future. In Martian Time-Slip Philip K. Dick uses power politics and extraterrestrial real estate scams, adultery, and murder to penetrate the mysteries of being and time.

    They are 16 humans in a distant world about to be enveloped by an eruption of violence--horror and murder oddly complemented by a bizarre unforgiving love. But justice is not all that's about to be found. Judgment is coming and the 16 unsuspecting ones are on the threshold of the murdered star.

    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
