Sigma underground werewolf leader Adrian is charged with murdering Lucas, her Alpha husband, and imprisoned in the Black Tower for trial. Ethan, a Delta scribe tasked with taking statements, recognizes Adrian as the person who pulled him out of a fire years earlier during the tower’s security check. The deeper Ethan digs into the case, the more certain he becomes that Adrian is innocent. Between interrogation rooms and the infirmary, as he sorts out timelines and digs into the late husband’s dark secrets, the two cross every line separating protocol, carnal desire and mutual trust. When evidence exposes the real killer, Ethan betrays the Black Tower and flees alongside Adrian—only to discover that an even bigger cage awaits them beyond the tower walls.
