All the world is a puzzle, and Mike Brink—a celebrated and ingenious puzzle constructor—understands its patterns like no one else. Once a promising Midwestern football star, Brink was transformed by a traumatic brain injury that caused a rare medical condition: acquired savant syndrome. The injury left him with a mental superpower—he can solve puzzles in ways ordinary people can't. But it also left him deeply isolated, unable to fully connect with other people. Everything changes after Brink meets Jess Price, a woman serving thirty years in prison for murder who hasn't spoken a word since her arrest five years before. When Price draws a perplexing puzzle, her psychiatrist believes it will explain her crime and calls Brink to solve it.
