More than 50 years after publishing his first story, Hugo Award-winning author Asimov remains one of the great names in science fiction. Almost single-handedly he transformed the field from the romantic and Gothic legacy of Jules Verne and Edgar Rice Burroughs into the rational, clear-minded genre that exists today. This selection of some of Asimov's most enduring and unforgettable stories is read by the author himself. These vintage tales encompass the full range of Asimov's versatility, while displaying his puckish sense of humor.

Now a 15-year-old Rotorian girl has learned of the dire threat that nemesis poses to Earth’s people - but she is prevented from warning them.

In what is considered one of Heinlein's most hair-raising, thought-provoking, and outrageous adventures, the master of modern science fiction tells the strange story of an even stranger world.

But that's the problem with the inevitable: it always happens.

One ad in particular leapt out at him: "Are you a coward? This is not for you. We badly need a brave man. He must be 23 to 25 years old, in perfect health, at least six feet tall, weigh about 190 pounds, fluent English with some French, proficient with all weapons, some knowledge of engineering and mathematics essential...."

After the fall of the American Ayatollahs as foretold in Stranger in a Strange Land and chronicled in Revolt in 2100, the United States of America at last fulfills the promise inherent in its first Revolution: for the first time in human history there is a nation with Liberty and Justice for All. No one may seize or harm the person or property of another, or invade his privacy, or force him to do his bidding. Americans are fiercely proud of their re-won liberties and the blood it cost them; nothing could make them forswear those truths they hold self-evident. Nothing except the promise of immortality…
