Brandon Thorpe and Sabrina Rivers Thorpe have enjoyed six months of wedded bliss, but Sabrina's been keeping a secret. Her transformation into a vampire created a magical disturbance in the Underworld. Now, Death is coming for what's his. But is Death the only thing stalking Sabrina? Brandon and Hadrian, Sabrina's father, bring in Delilah, a demon, to act as detective and magical keeper. But Sabrina's bloodlines are unique, and magic responds to her in unpredictable ways. Have Brandon's efforts to keep her safe just made her a bigger, more valuable target? Is she even a vampire at all? To what depths will Sabrina have to go to satisfy Death's demands? Can she do it using her own powers? Can Brandon find a way to keep the Underworld from claiming Sabrina for its own? Can they even survive, if he doesn't? What if Death isn't the only one looking to do her harm? In the darkness, can a single jewel save them all?
