Twenty years after the discovery of artificial wormholes launches Earth space exploration to unforeseeable heights, Starplex Director Keith Lansing investigates a mysterious vessel that soon threatens the station with intergalactic war.

    Within hours after the Lunar observatory picked up a strange new X-ray source in Cygnus, the disastrous picture was clear. An immense object was hurtling toward the Solar System at nearly the speed of light...and its intense radiation would surely wipe Earth free of all life within six months.There was nothing anyone could do.Then, incredibly, the rogue that had appeared out of nowhere suddenly changed its trajectory and stopped in the area of Jupiter.And that was flatly impossible!

    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

    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.

    Now it occurs to me that my memoirs of the 25th Century may have an equal interest 500 years from now—particularly in view of that unique perspective from which I have seen the 25th Century, entering it as I did, in one leap across a gap of 492 years. This statement requires elucidation. There are still many in the world who are not familiar with my unique experience. Five centuries from now there may be many more, especially if civilization is fated to endure any worse convulsions than those which have occurred between 1975 A.D. and the present time. I should state therefore, that I, Anthony Rogers, am, so far as I know, the only man alive whose normal span of eighty-one years of life has been spread over a period of 573 years. To be precise, I lived the first twenty-nine years of my life between 1898 and 1927; the other fifty-two since 2419. The gap between these two, a period of nearly five hundred years, I spent in a state of suspended animation, free from the ravages of katabolic processes, and without any apparent effect on my physical or mental faculties.

    But, logically, there would be times--

    After the explotion, searchers sifted through the immense pile of debris ... to discover a fantastically instrumented capsule, and a strangely human pilot, stone dead. Bowden Karvel's theory, that the capsule's port of origin lay in the distant future, seemed a plausible explanation. But while investigating, the capsule was accidentally dispatched again through time ... only to reappear with an alien navigator, this time destroying a small French town. One thing seemed imperative: a human operator must man the intricate controls of the capsule, riding it forward to its mysterious point of origin. And Bowden Karvel seemed the perfect choice to make the trip...

    It's the beginning of an incredible odyssey in which John Carter, a gentleman from Virginia and a Civil War veteran, unexpectedly finds himself on to the red planet, scene of continuing combat among rival tribes. Captured by a band of six-limbed, green-skinned savage giants called Tharks, Carter soon is accorded all the honor of a chieftain after it's discovered that his muscles, accustomed to Earth's greater gravity, now give him a decided advantage in strength. And when his captors take as prisoner Dejah Thoris, the lovely human-looking princess of the city of Helium, Carter must call upon every ounce of strength, courage, and ingenuity to rescue her-before Dejah becomes the slave of the depraved Thark leader, Tal Hajus!Excerpt:Her oval face was beautiful in the extreme, her every feature finely chisled and exquisite, her eyes large and lustrous and her head surmounted by a mass of coal black, waving hair, caught loosely into a strange yet becoming coiffure. Similar in face and figure to women of Earth, she was nevertheless a true Martian--and prisoner of the fierce green giants who held me captive, as well!

    "Anda's Game" is a spin on the bizarre new phenomenon of "cyber sweatshops," in which people are paid very low wages to play online games all day in order to generate in-game wealth, which can be converted into actual money. Another tale tells of the heroic exploits of "sysadmins" — systems administrators — as they defend the cyber-world, and hence the world at large, from worms and bioweapons. And yes, there is a story about zombies, too.

    Pull up a chair, grab a glass of your favorite, and listen to the stories spun by time travelers, cybernetic aliens, telepaths...and a bunch of regular folks on a mission to save the world, one customer at a time.Callahan's Crosstime Saloon contains the following stories, virtually all of which were published in Analog Science Fiction and Fact: * "The Guy With the Eyes" * "The Time-Traveler" * "The Centipede's Dilemma" * "Two Heads Are Better Than One" * "The Law Of Conservation of Pain" * "Just Dessert" * "A Voice is Heard in Ramah..." * "Unnatural Causes" * "The Wonderful Conspiracy"

    Still, like everything else in the Budayeen, he’s available…for a price.For a new kind of killer roams the streets of the Arab ghetto, a madman whose bootlegged personality cartridges range from a sinister James Bond to a sadistic disemboweler named Khan. And Marid Audrian has been made an offer he can’t refuse.The 200-year-old “godfather” of the Budayeen’s underworld has enlisted Marid as his instrument of vengeance. But first Marid must undergo the most sophisticated of surgical implants before he dares to confront a killer who carries the power of every psychopath since the beginning of time.Wry, savage, and unignorable, When Gravity Fails was hailed as a classic by Effinger’s fellow SF writers on its original publication in 1987, and the sequence of “Marid Audrian” novels it begins were the culmination of his career.

    They called him Charlie. He had big eyes, abundant body hair and fairly long nostrils. His skeletal body was found clad in a bright red spacesuit, hidden in a rocky grave. They didn't know who he was, how he got there, or what had killed him. All they knew was that his corpse was 50,000 years old; and that meant that this man had somehow lived long before he ever could have existed!

    Clarke In a moving story of sacrifice and triumph, human scientists establish a relationship with intelligent lifeforms--the cheela--living on Dragon's Egg, a neutron star where one Earth hour is equivalent to hundreds of their years. The cheela culturally evolve from savagery to the discovery of science, and for a brief time, men are their diligent teachers.Praise for Dragon's Egg"Bob Forward writes in the tradition of Hal Clement's Mission of Gravity and carries it a giant step (how else?) forward."--Isaac Asimov "Dragon's Egg is superb. I couldn't have written it; it required too much real physics."--Larry Niven "This is one for the real science-fiction fan."--Frank Herbert"Robert L. Forward tells a good story and asks a profound question. If we run into a race of creatures who live a hundred years while we live an hour, what can they say to us or we to them?"--Freeman J. Dyson"Forward has impeccable scientific credentials, and . . . big, original, speculative ideas."--The Washington Post
