Psychohistorical Crisis is a science fiction novel by American-Canadian writer Donald Kingsbury, published by Tor Books in 2001. An expansion of his 1995 novella "Historical Crisis", it is a re-imagining of the world of Isaac Asimov's Foundation series, set after the establishment of the Second Empire. The book is neither officially authorized by Asimov's estate (as they had previously done with the Second Foundation Trilogy), nor is it intended to be recognized as part of his continuity.
Psychohistorical Crisis was the 2002 winner of the Prometheus Award.
Eron Osa had been one of the Pscholars, the secret leaders behind the Second Empire of humanity. For a crime he cannot remember, he was sentenced, not to death, but to the removal of his fam, his symbiotic computer mind. Without the augmentation of his brain by his electronic familiar, he can barely function on Splendid Wisdom, the capital of the Empire. Without one, simply navigating the streets of the planetary megalopolis is nearly impossible. Worse, the traumatic removal has stolen large chunks of his memory, which were never stored in his biological brain. Eron must figure out what he did and why, and he must do so soon...
