It is a peaceful reign, held by compact and not by conquest. Again and again, when rebellion threatens the Terran Peace, the natives of the rebellious world have turned against their own people and sided with the men of Terra; not from fear, but from a sense of dedication. There has never been open war. The battle for these worlds is fought in the minds of a few men who stand between worlds; bound to one world by interest, loyalties and allegiance; bound to the other by love. Such a world is Wolf. Such a man was Race Cargill of the Terran Secret Service… At one time Race Cargill had been the best Terran Intelligence agent on the complex and mysterious planet of Wolf. He had repeatedly imperiled his life amongst the half-human and non-human creatures of the sullen world. And he had repeatedly accomplished the fantastic missions until his name was emblazoned with glory. But that had all seemingly ended. For six long years he'd sat behind a boring desk inside the fenced-in Terran Headquarters, cut off there ever since he and a rival had scarred and ripped each other in blood-feud. But when The Door Through Space swung suddenly open, the feud was on again—and with it a plot designed to check and destroy the Terran Empire.

    The Separation suggests an alternate history lying along a road not taken in World War II. But there are complications. In 1999, history author Stuart Gratton is intrigued by a minor mystery of the European war which ended on 10 May 1941. The British-German armistice signed that month has had far-reaching consequences, including a resettlement of European Jews in Madagascar. In 1936, the identical twin brothers Joe and Jack Sawyer win a rowing medal for Britain in the Berlin Olympics: it's presented to them by Rudolf Hess. The brothers are separated not only by a twin's fierce need "to be treated as a separate human being", but by sexual rivalry and even ideology. When war breaks out Jack becomes a gung-ho bomber pilot, Joe a conscientious objector. Still they're inescapably linked, and sometimes confused. Both suffer injuries and hauntingly similar ambulance journeys. Churchill writes a puzzled memo (later unearthed by Gratton) about the anomaly of a registered-pacifist Red Cross worker flying planes for Bomber Command. Hess has significant, eventually incompatible meetings with both men. Contradictions are everywhere. As in his magical 1995 novel The Prestige Priest is fruitfully fascinated by the legerdemain of twins, doubles, impostors, symmetrical roles. Churchill's double briefly appears. So does the famous conspiracy theory that the Hess who flew to Britain with his quixotic peace deal wasn't the real Hess ring true? Clearly The Separation was impressively, extensively researched. Its evocations of bombing raids--from either side of the bomb sites--are memorable. The unfolding story strands become increasingly disorienting and hallucinatory; the easy escape route of dismissing one strand as delusion is itself subtly undermined. The Separation is filled with a sense of the precariousness of history; of small events and choices with extraordinary consequences. --David Langford

    That single tragedy set off a whole series of events, resulting in the Spanish Armada's defeat of England and subsequent demise of Protestantism. Now it's the 20th century, and the Church of Rome reigns supreme. People live a pastoral existence of guilds and farming, with technology held back to the level of the steam locomotive and primitive radio. Still, science cannot be held back forever...a revolution is building.

    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.

    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.

    Clarke of Last and First Men. This masterpiece of science fiction by British philosopher and writer Olaf Stapledon (1886–1950) is an imaginative, ambitious history of humanity's future that spans billions of years. Together with its follow-up, Star Maker, it is regarded as the standard by which all earlier and later future histories are measured.The protagonist of this compelling novel is humanity itself, stripped down to sheer intelligence. It evolves through the ages: rising to pinnacles of civilization, teetering on the brink of extinction, surviving onslaughts from other planets and a decline in solar energy, and constantly developing new forms, new senses, and new intellectual abilities. From the present to five billion years into the future, this romance of humanity abounds in profound and imaginative thought.

    It was a simple mission. A standard crew.THE PROBLEMKai and his beautiful co-leader Varian, the best xenob-vet in the business, followed all the standard procedures -- but the results of their investigations were totally unexpected. Not only were the planet's creatures larger than anyone had anticipated and the geological finds smaller, but the rescue ship had inexplicably disappeared.THE NIGHTMAREThen suddenly on a world of giant swamp creatures and deadly predators, a curious change had come over many of the members of the ARCT-10 crew... a change that would lead all of them, in one way or another, into the primitive darkness of a future world.

    Anti-Gerasone halts the aging process and prevents people from dying of old age as long as they keep taking it; as a result, America now suffers from severe overpopulation and shortages of food and resources. With the exception of the very wealthy, most of the population appears to survive on a diet of foods made from processed seaweed and sawdust. Gramps Ford, his chin resting on his hands, his hands on the crook of his cane, was staring irascibly at the five-foot television screen that dominated the room. On the screen, a news commentator was summarizing the day's happenings. Every thirty seconds or so, Gramps would jab the floor with his cane-tip and shout, "Hell, we did that a hundred years ago!" Emerald and Lou, coming in from the balcony, where they had been seeking that 2185 A.D. rarity--privacy--were obliged to take seats in the back row, behind about a dozen relatives with whom they shared the house. All save Gramps, who was somewhat withered and bent, seemed, by pre-anti-gerasone standards, to be about the same age--somewhere in their late twenties or early thirties. Gramps looked older because he had already reached 70 when anti-gerasone was invented. He had not aged in the 102 years since. "Next one shoots off his big bazoo while the TV's on is gonna find hisself cut off without a dollar--" his voice suddenly softened and sweetened--"when they wave that checkered flag at the Indianapolis Speedway, and old Gramps gets ready for the Big Trip Up Yonder." He sniffed sentimentally, while his heirs concentrated desperately on not making the slightest sound. For them, the poignancy of the prospective Big Trip had been dulled somewhat, through having been mentioned by Gramps about once a day for fifty years.

    In the first installment, Carter wins the affections of the "princess of Mars" and the respect of the Martian warlords whom he befriends. The excitement continues in The Gods of Mars when Carter engages the Black Pirates in airborne combat above the dead seas of Mars and leads a revolt to free the Martian races from a religion that thrives on living sacrifices. In the third book, Warlord of Mars, Carter overcomes the forces of evil that would destroy the planet. By the end of the trilogy the Martians all clamor for a triumphant John Carter to be their king.About the Author:Born in Chicago, Illinois, on September 1, 1875, Edgar Rice Burroughs grew to maturity during the height of the Industrial Revolution and witnessed the emergence of the United States as a twentieth-century world power. Hailing from a well-to-do family, Burroughs was given an aristocratic education steeped in Latin and Greek, but he was drawn more to an itinerant life of adventure than to a life in the boardroom. The author of Tarzan of the Apes (1912), Burroughs did not confine himself to a single genre; he also wrote medieval romances (The Outlaw of Torn, 1914), westerns (The War Chief of the Apaches, 1927), and mainstream novels (The Girl from Hollywood, 1922).

    Just another day in the Dilemma Prison. Rescued by the mysterious Mieli and her flirtatious spacecraft, Jean is taken to the Oubliette, the Moving City of Mars, where time is a currency, memories are treasures, and a moon-turned-singularity lights the night. Meanwhile, investigator Isidore Beautrelet, called in to investigate the murder of a chocolatier, finds himself on the trail of an arch-criminal, a man named le Flambeur...Indeed, in his many lives, the entity called Jean le Flambeur has been a thief, a confidence artist, a posthuman mind-burgler, and more. His origins are shrouded in mystery, but his deeds are known throughout the Heterarchy, from breaking into the vast Zeusbrains of the Inner System to stealing rare Earth antiques from the aristocrats of Mars. In his last exploit, he managed the supreme feat of hiding the truth about himself from the one person in the solar system hardest to hide from: himself. Now he has the chance to regain himself in all his power—in exchange for finishing the one heist he never quite managed.The Quantum Thief is a breathtaking joyride through the solar system several centuries hence, a world of marching cities, ubiquitous public-key encryption, people who communicate via shared memory, and a race of hyper-advanced humans who originated as an MMORPG guild. But for all its wonders, The Quantum Thief is also a story powered by very human motives of betrayal, jealousy, and revenge.
