by Isaac Asimov
For twelve thousand years the Galactic Empire has ruled supreme. Now it is dying. But only Hari Sheldon, creator of the revolutionary science of psychohistory, can see into the futureâ€”to a dark age of ignorance, barbarism, and warfare that will last thirty thousand years. To preserve knowledge and save mankind, Seldon gathers the best minds in the Empireâ€”both scientists and scholarsâ€”and brings them to a bleak planet at the edge of the Galaxy to serve as a beacon of hope for a fututre generations. He calls his sanctuary the Foundation.
But soon the fledgling Foundation finds itself at the mercy of corrupt warlords rising in the wake of the receding Empire. Mankind's last best hope is faced with an agonizing choice: submit to the barbarians and be overrunâ€”or fight them and be destroyed.
