Shape-shifting werewolf and vampire Riley Jenson is through with death - causing it, solving it, surviving it. Her soul mate, Kye Murphy, is dead - and at Riley's own hands. Not even the seductive embrace of her vampire lover, Quinn, can fully ease her mind, for she has begun questioning everything that makes her Riley - including her job at the Directorate.

But then ritualistically slain bodies of ex-cons start turning up. Reluctantly, Riley takes the case, but something even worse is waiting in the wings. For a vicious enemy from her past is determined to strip Riley of everything that gives her life any meaning: her lover, her twin brother - and even her own identity. Can Riley survive this ultimate assault? All she knows is, she must fight one last time to find answers, before everything goes dark forever . . .
