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...
