The sequel to Blake Crouch's bestselling book Dark Matter, Recursion is a breath-taking examination of memory and what it means to be human. Gregg Hurwitz, the author of Orphan X, said of Recursion: "Recursion takes mind-twisting principles and embeds them in a very emotional novel about time and loss and pain and most importantly, the splendour of the human heart." It initially appears to be an illness. An outbreak that has no known cause and sends its victims insane with memories of a life they never had. The force that is sweeping the globe, however, is not a pathogen. A remarkable revelation has just just begun to shock the world, and more than just our minds are at risk.
