Everyone is a puzzle, and Mike Brink—a renowned and ingenious puzzle builder—understands his patterns like no other. Once a rising football star, Brink was completely changed by a traumatic brain injury that caused him a rare disease: Acquired Savant Syndrome. The injury gave him a mental superpower: being able to solve puzzles, calculate equations, and see patterns that normal people can't perceive. But the syndrome has also left him deeply isolated, unable to connect with other people. Everything changes when Brink meets Jess Price, a woman sentenced to thirty years in prison for murder. Traumatized by the crime, Price has not spoken since her arrest five years ago. When she draws an amazing puzzle, her psychiatrist thinks she can explain the crime she committed and calls Brink to solve it. What begins as a desire to crack a strange and seductive code quickly turns into an obsession with the woman who drew the puzzle. Price quickly reveals that there is something much more urgent - and more dangerous - behind her silence, driving Brink to search for the truth. Traveling from a women's prison in upstate New York to 19th century Prague, passing through the secret rooms of the Pierpoint Morgan Library, The Master of Riddles is a seductive and addictive thriller in which humanity is at stake.
