For twelve thousand years the Galactic Empire has ruled supreme. Now it is dying. But only Hari Seldon, creator of the revolutionary science of psychohistory, can see into the future—to a dark age of ignorance, barbarism, and warfare that will last thirty thousand years. To preserve knowledge and save humankind, Seldon gathers the best minds in the Empire—both scientists and scholars—and brings them to a bleak planet at the edge of the galaxy to serve as a beacon of hope for future generations. He calls his sanctuary the Foundation.

It is the year 12,020 GE and Emperor Cleon I sits uneasily on the Imperial throne of Trantor. Here in the great multidomed capital of the Galactic Empire, 40 billion people have created a civilization of unimaginable technological and cultural complexity. Yet Cleon knows there are those who would see him fall - those whom he would destroy if only he could read the future.

As Hari Seldon struggles to perfect his revolutionary theory of psychohistory and ensure a place for humanity among the stars, the great Galactic Empire totters on the brink of apocalyptic collapse. Caught in the maelstrom are Seldon and all he holds dear, pawns in the struggle for dominance. Whoever can control Seldon will control psychohistory - and with it the future of the galaxy.

At last, the costly and bitter war between the two Foundations has come to an end. Now two exiled citizens of the Foundation - a renegade Councilman and a doddering historian - set out in search of the mythical planet Earth. Meanwhile, someone - or something - outside of both Foundations seems to be orchestrating events to suit its own ominous purpose.

This classic science fiction masterwork by Isaac Asimov weaves stories about robots, humanity, and the deep questions of existence into a novel of shocking intelligence and heart.

From Heinlein's thought-provoking "Searchlight" and Clarke's dreamy "Reverie", to Asimov's ingenious "Super-Neutron", Bradbury's chilling "Zero Hour", and Zelazny's poetic masterpiece "A Rose for Ecclesiastes", each story explores deep questions of technology, humanity, and the unknown. Carefully curated to represent both iconic tales and lesser-known gems, this volume offers something for every science fiction reader—whether a newcomer or a lifelong fan.

Golan Trevize, former councilman of the First Foundation, has chosen the future, and it is Gaia. A superorganism, Gaia is a holistic planet with a common consciousness so intensely united that every dewdrop, every pebble, every being, can speak for all - and feel for all. It is a realm in which privacy is not only undesirable, it is incomprehensible. But is it the right choice for the destiny of mankind? While Trevize feels it is, that is not enough. He must know.
