Foundation #1-3: Book Series by Isaac Asimov
The 3-book set trade paperback novels includes the below titles:
Foundation (ISBN 9780553382570): For twelve thousand years the Galactic Empire has ruled supreme. Now it is dying. Only Hari Seldon, creator of the revolutionary science of psychohistory, can see into the future—a dark age of ignorance, barbarism, and warfare that will last thirty thousand years. To preserve knowledge and save humanity, 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 this sanctuary the Foundation.
But soon the fledgling Foundation finds itself at the mercy of corrupt warlords rising in the wake of the receding Empire. And mankind’s last best hope is faced with an agonizing choice: submit to the barbarians and live as slaves—or take a stand for freedom and risk total destruction.
Foundation and Empire (ISBN 9780553382587): Led by its founding father, the great psychohistorian Hari Seldon, and taking advantage of its superior science and technology, the Foundation has survived the greed and barbarism of its neighboring warrior-planets. Yet now it must face the Empire—still the mightiest force in the Galaxy even in its death throes. When an ambitious general determined to restore the Empire’s glory turns the vast Imperial fleet toward the Foundation, the only hope for the small planet of scholars and scientists lies in the prophecies of Hari Seldon.
But not even Hari Seldon could have predicted the birth of the extraordinary creature called The Mule—a mutant intelligence with a power greater than a dozen battle fleets . . . a power that can turn the strongest-willed human into an obedient slave.
Second Foundation (ISBN 9780553382594): After years of struggle, the Foundation lies in ruins—destroyed by the mutant mind power of the Mule. But it is rumored that there is a Second Foundation hidden somewhere at the end of the Galaxy, established to preserve the knowledge of mankind through the long centuries of barbarism. The Mule failed to find it the first time—but now he is certain he knows where it lies.
The fate of the Foundation rests on young Arcadia Darell, only fourteen years old and burdened with a terrible secret. As its scientists gird for a final showdown with the Mule, the survivors of the First Foundation begin their desperate search. They too want the Second Foundation destroyed . . . before it destroys them.
