(Part of the original Foundation Trilogy, winner of the Hugo Award for Best All-Time Novel Series) The Foundation is in tatters, conquered by a mutant of incredible power known as the Mule, in this third novel of the Foundation saga-the closing chapter of the original trilogy, acknowledged as a central masterwork of modern science fiction with a special Hugo Award for Best All-Time Novel Series. But Hari Seldon, the brilliant prophet who foresaw the need for the Foundation, also built a Second Foundation, containing the knowledge of his predictive science of psychohistory, whose laws only remain valid if they are secret. The Foundation's survivors are desperately seeking the Second Foundation, hoping to save humanity-but the Mule is focusing his full energies on finding it first.
