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.

    When famous adventurer Sir Richard Francis Burton dies, the last thing he expects to do is awaken naked on a foreign planet along the shores of a seemingly endless river. But that's where Burton and billions of other humans (plus a few nonhumans) find themselves as the epic Riverworld saga begins. It seems that all of Earthly humanity has been resurrected on the planet, each with an indestructible container that provides three meals a day, cigarettes, alcoholic beverages, a lighter, and the odd tube of lipstick. But why? And by whom? That's what Burton and a handful of fellow adventurers are determined to discover as they construct a boat and set out in search of the river's source, thought to be millions of miles away. Although there are many hardships during the journey--including an encounter with the infamous Hermann Goring--Burton's resolve to complete his quest is strengthened by a visit from the Mysterious Stranger, a being who claims to be a renegade within the very group that created the Riverworld. The stranger tells Burton that he must make it to the river's headwaters, along with a dozen others the Stranger has selected, to help stop an evil experiment at the end of which humanity will simply be allowed to die. --Craig E.

    For his crimes he is required, as is the custom of the 25th century, to wander the world being as useful as he can to all he meets. Carlyle Foster is a sensayer--a spiritual counselor in a world that has outlawed the public practice of religion, but which also knows that the inner lives of humans cannot be wished away.The world into which Mycroft and Carlyle have been born is as strange to our 21st-century eyes as ours would be to a native of the 1500s. It is a hard-won utopia built on technologically-generated abundance, and also on complex and mandatory systems of labeling all public writing and speech. What seem to us normal gender distinctions are now distinctly taboo in most social situations. And most of the world's population is affiliated with globe-girdling clans of the like-minded, whose endless economic and cultural competition is carefully managed by central planners of inestimable subtlety. To us it seems like a mad combination of heaven and hell. To them, it seems like normal life.And in this world, Mycroft and Carlyle have stumbled on the wild card that may destablize the system: the boy Bridger, who can effortlessly make his wishes come true. Who can, it would seem, bring inanimate objects to life...

    His work is leading General Technics to the forefront of global domination, both in the marketplace and politically—it's about to take over a country in Africa. Donald Hogan is his roommate, a seemingly sheepish bookworm. But Hogan is a spy, and he's about to discover a breakthrough in genetic engineering that will change the world ... and kill him. These two men's lives weave through one of science fiction's most praised novels. Written in a way that echoes John Dos Passos' U.S.A. Trilogy, Stand on Zanzibar is a cross-section of a world overpopulated by the billions. Where society is squeezed into hive-living madness by god-like mega computers, mass-marketed psychedelic drugs, and mundane uses of genetic engineering. Though written in 1968, it speaks of 2010, and is frighteningly prescient and intensely powerful.This edition comes with a tipped in collectors' note and an introduction by David Brin.

Since childhood, the young men have been shaped by stories that their late father was a Traveler, one of a small band of prophets who have vastly influenced the course of history. Travelers are able to attain pure enlightenment, and have for centuries ushered change into the world. Gabriel and Michael, who may have inherited their father's gifts, have always protected themselves by living “off the Grid”—that is, invisible to the real-life surveillance networks that monitor people in our modern society.Summoned by her ailing father, Maya is told of the existence of the brothers. The Corrigans are in severe danger, stalked by powerful men known as the Tabula—ruthless mercenaries who have hunted Travelers for generations.

A colossal battle looms—one that will reveal not only the identities of Gabriel and Michael Corrigan but also a secret history of our time.Moving from the back alleys of Prague to the heart of Los Angeles, from the high deserts of Arizona to a guarded research facility in New York, The Traveler explores a parallel world that exists alongside our own.
