One had created the other - normal humans had experimented in forced evolution and had produced the ler, a sort of supermen race, but pacifistic and contemplative. The ler fled from the turbulent worlds of homo sapiens and established their own quiet planetary colonies. Which made it all the more inexplicable when reports came in of fierce planetary marauders, looting and burning, who were of ler ancestry. The existence of barbarian lers was a contradiction in terms. And the search for their reasons for existence was to take a human male and a ler female into an expedition into strange worlds and the unsuspected bypasses of all the systems of science and philosophy.

    if the might of the Federation met the advanced weaponry of the aliens... the inevitable clash would surely destroy all life in the solar system!"

    A few human beings were left on the deserted earth along with countless robots. The human beings--including a small tribe of American Indians--made do. The Indians returned to ancient tribal ways, the others stubbornly tried to rebuild technology. The robots--some stayed with the humans performing their service functions, some went off to create a religiously-based society of their own. Millennia later, a star-traveler returns from the center of the universe. The people of earth had been found and were planning to return. But something else had been found, too--the central intelligence of the universe!

    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

    That he will never contract a disease, an infection, or even a cold. That because he will never die, he must surrender the right to live.For Dr. Russell Pearce, the price is eternal suspicion.

He also fears what will happen should Cartwright’s miraculous blood fall into the wrong hands.For the wealthy and powerful, no price is too great. Immortality is now a fact rather than a dream. But the only way to achieve it is to own it exclusively. And that means hunting down and caging the elusive Cartwright, or one of his offspring.

    D. James's trademark suspense, insightful characterization, and riveting storytelling, The Children of Men is a story of a world with no children and no future. The human race has become infertile, and the last generation to be born is now adult. Civilization itself is crumbling as suicide and despair become commonplace. Oxford historian Theodore Faron, apathetic toward a future without a future, spends most of his time reminiscing. Then he is approached by Julian, a bright, attractive woman who wants him to help get her an audience with his cousin, the powerful Warden of England. She and her band of unlikely revolutionaries may just awaken his desire to live . . . and they may also hold the key to survival for the human race.

    The White Plague, a marvelous and terrifyingly plausible blend of fiction and visionary theme, tells of one man who is pushed over the edge of sanity by the senseless murder of his family and who, reappearing several months later as the so-called Madman, unleashes a terrible plague upon the human race—one that zeros in, unerringly and fatally, on women.

    He's also expendable - at least in the eyes of the Secretary of Traffic for the Nation of California. Tanner doesn't care much for those eyes. You'd also never mistake Hell Tanner for a humanitarian. Facing life in prison for his various crimes, he's given a choice; rot away his remaining years in a tiny jail cell, or drive cross-country and deliver a case of antiserum to the plague-ridden people of Boston, Massachusetts...if anyone is still alive there to receive it, that is. The chance of a full pardon does wonders for getting his attention. And don't mistake this mission of mercy for any kind of normal road trip - not when there are radioactive storms, hordes of carniverous beasts, and giant, mutated scorpions to be found along every deadly mile between Los Angeles and the East Coast. But then, this is no normal part of America, you see. This is DAMNATION ALLEY...

    The aliens put their ship into orbit around the moon, peacably ignoring frantic human excitement, and asked to see someone who knew the stars. Earth sent Bradley Reynolds, 52, officially retired, a man who knew the stars as well as any man could. But the aliens wanted more than Reynolds could give. They wanted to know whether the sun loves us.For Bradley Reynolds, it was the beginning of a life-long quest for alien intelligence, for beings who could speak to him with that wonderful Otherness. On Mars, on Jupiter, on Titan he would find hints of what he sought, and what he would find in the end was a tranformation so glorious as to be far beyond his capacity to dream.
