Some nights never end.

Some desires never die. . . .

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.

Now, the ritualistically slain bodies of ex-cons have started turning up. Reluctantly, Riley takes the case, but something even worse is waiting in the wings. A vicious enemy from her past is determined to strip Riley of everything that gives her life any meaning: her lover, her 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.
