When a stranger attempting to deliver a cryptic message is shot dead at his dinner table, Richard Ames is thrown headfirst into danger, intrigue, and other dimensions where Lazarus Long still thrives, where Jubal Harshaw lives surrounded by beautiful women, and where a daring plot to rescue the sentient computer called Mike can change the direction of all human history.

The wickedest, most wonderful science fiction story ever created in our - or any - time. Anything can begin at a party in California - and everything does in this bold masterwork by a grand master of science fiction. When four supremely sensual and unspeakably cerebral humans - two male, two female - find themselves under attack from aliens who want their awesome quantum breakthrough, they take to the skies - and zoom into the cosmos on a rocket roller-coaster ride of adventure, danger, ecstasy, and peril.

Maureen Johnson, the somewhat irregular mother of Lazarus Long, wakes up in bed with a man and a cat. The cat is Pixel, well-known to fans of the New York Times best seller The Cat Who Walks through Walls. The man is a stranger to her, and besides that, he is dead.

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…

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. It is 21st-century Luna, a harsh penal colony where a revolt is plotted between a bashful computer and a ragtag collection of maverick humans, a revolt that goes beautifully until the inevitable happens. But that's the problem with the inevitable: it always happens.

Friday, a secret courier, is thrown into an assignment under the command of her employer, a man she knows only as "Boss."

In America's disunion, Friday keeps her balance nimbly with quick, expeditious solutions as she conquers one calamity and scrape after another.

Winner of the 1961 Hugo Award for Best Novel and widely considered one of the most accomplished, powerful, and enduring classics of modern speculative fiction, Walter M. Miller’s A Canticle for Leibowitz is a true landmark of 20th-century literature—a chilling and still-provocative look at a postapocalyptic future.

Robert A. Heinlein wrote The Number of the Beast, which was published in 1980. In the book Zeb, Deety, Hilda, and Jake are ambushed by the alien "Black Hats" and barely escape with their lives on a specially configured vehicle (the Gay Deceiver) which can travel along various planes of existence, allowing them to visit parallel universes. However, unknown to most fans, Heinlein had already written a "parallel" novel about the four characters and parallel universes in 1977.

Robert A. Heinlein is widely and justly regarded as the greatest practitioner of the art of science fiction who has ever lived. Here are two of his greatest short novels: Gulf, in which the greatest super-spy of them all is revealed as the leader of a league of supermen and women who can’t quite decide what to do with the rest of us. And Lost Legacy, in which it is proved that we are all members of that league - or would be, if we but had eyes to see.
