It's been two weeks since Polly St. James went missing. Everyone has ruled her a runaway - but not Maren, her best friend and roommate. Polly had a secret that she was about to share before she disappeared― something to do with the elite, ultra-rich crowd at their school, Torrey-Wells. Then Maren finds an envelope hidden among Polly's things: an invitation to the Gamemaster's Society. Maren is certain her classmates in the Society know the truth about what happened to Polly. Once she makes it in, she discovers a world she never knew, where Society members compete in high-stakes games for unheard-of rewards―Ivy League connections, privileges, favors. For every win, Maren receives a clue about Polly. And as she keeps winning, she begins to see just how powerful the Society's game is―bigger and deadlier than she ever imagined. They see, they know, they control. And they kill.
