Two novels that precede the main Academy trilogy by Isaac Asimov. The young scientist Hari Seldon discovers algorithms that allow mathematical predictions of social development. He calls it psychohistory. But for Emperor Cleon the First, psychohistory is an opportunity to predict and direct the development of his Galactic Empire. This is why Seldon, as the main theorist of psychohistory, becomes the most wanted man in the colonized universe. He will not only create the Academy, but also prevent the political crisis that almost brought down the Galactic Empire. “The epic story of the rise and fall of the galactic empire of the future.” – IO9 “An amazing story about how knowledge – understanding the functioning of our society – can change history and make the world a better place.” – THE GUARDIAN “The novel features Asimov himself, personified in Seldon. The enormous intellect and interest of the psychohistorian, his concern for the future of science in dark times, his disappointment in the face of death - all this rings especially poignant and truthful.” - PUBLISHERS WEEKLY "A fascinating portrait of a unique man against the backdrop of the 'rise and fall of a galactic empire.'" – LIBRARY JOURNAL “A touching farewell to a great science fiction writer.” – KIRKUS REVIEWS
