Guardian Riley Jenson always seems to face the worst villains. And this time's no different. For it's no ordinary sorceress who can raise the dead to do her killing. But that's exactly what Riley expects to find at the end of a trail of female corpses used - and discarded - in a bizarre ritual of evil. With pressure mounting to catch the fiend, the last thing Riley needs is the heat of the upcoming full moon bringing her werewolf hormones to a boil - or the reappearance of a sexy bounty hunter, the rogue wolf Kye Murphy.

Riley has threatened Murphy with arrest if he doesn't back off the investigation, but it's Riley who feels handcuffed by Kye's lupine charm. Torn between her vamp and wolf natures, between her love for Quinn and her attraction to Kye, Riley knows she's courting danger and indulging the deadliest desires. For her hunt through the supernatural underworld will bring her face-to-face with what lurks in a darkness where even monsters fear to tread.
