Unaware that his revolutionary ideas have already marked him as the most dangerous man in the galaxy, Seldon becomes the unwitting target of Emperor Cleon I and the shadowy forces that seek to control the Empire's destiny. As political intrigue and ambition swirl around him, Seldon must navigate a treacherous landscape of power and deception while grappling with the profound implications of his own prophetic abilities. This prequel to Asimov's legendary Foundation series explores the origins of one of science fiction's most iconic concepts, revealing how one man's vision of the future sets in motion events that will reshape human civilization for millennia to come.

Foundation and Empire
Isaac Asimov
In the twilight of a galactic empire, the brilliant mathematician Hari Seldon foresees an impending dark age of barbarism and chaos that will last for thirty thousand years. To shorten this destructive era to a mere one thousand, he establishes two Foundations at opposite ends of the galaxy, dedicated to preserving the sum of human knowledge. This epic saga follows the trials and tribulations of the First Foundation as it navigates political intrigue, economic manipulation, and the rise of warlords, all while striving to fulfill Seldon's grand design.

While the Foundation's leaders scramble to maintain control and preserve their plan for a new galactic order, a hidden force known as the Second Foundation works in the shadows to guide humanity's future. A young prodigy, Arkady Darell, may hold the key to understanding and locating this elusive organization, but the path to salvation is fraught with peril and uncertainty.

Foundation's Edge
Isaac Asimov
Five centuries after Hari Seldon’s psychohistorical plan began, the Foundation has grown into a powerful interstellar force—but its expansion brings it into conflict with the hidden Second Foundation and an uncertain future. Councilman Golan Trevize is sent into exile with historian Janov Pelorat to search for the legendary origin world of humanity, while confronting questions that challenge the foundations of galactic civilization. Their journey leads through competing visions of order, freedom, destiny, and collective identity, as political intrigue and scientific speculation converge on a mystery with consequences for every world. Combining sweeping space opera with philosophical depth, the novel expands its celebrated future history into a provocative exploration of how societies choose—and shape—their future.

Foundation and Earth
Isaac Asimov
Golan Trevize, former Councilman of the First Foundation, has made his choice for humanity's future: Gaia, a superorganism where every particle of existence shares a unified consciousness and collective purpose. Yet certainty eludes him—he must know, not merely believe, that this choice is right. Convinced that the answer lies in discovering humanity's lost ancestral home, the legendary planet Earth, Trevize embarks on a perilous quest across the Galaxy to uncover the truth hidden in the shadows of galactic history. As he and his companions navigate the vast wilderness of space, they must confront the mystery of why Earth has vanished from all records and why Gaia's vast world-memory contains no trace of mankind's origins. In this epic conclusion to Asimov's Foundation saga, the search for Earth becomes a search for the very meaning of human destiny.
