Ama, Mark, and Justin—each witness to an unpunished murder—have seen their lives spiral downward in grief in the aftermath. When a Fury summons them to Salem, she promises that if they obey her Revenger’s rules, she will grant them power to avenge their losses and get their lives back. The catch: they’ll have to become killers themselves. But even as they follow her plan, they realize a larger game is being played, and that they may be secrets they don’t yet know which could cost them everything.
