It should be the best time of half-vampire Cat Crawfield`s life. With her undead lover Bones at her side, she`s successfully protected mortals from the rogue undead. But though Cat`s worn disguise after disguise to keep her true identity a secret from the brazen bloodsuckers, her cover`s finally been blown, placing her in terrible danger. As if that wasn`t enough, a woman from Bones`s past is determined to bury him once and for all. Caught in the crosshairs of a vengeful vamp, yet determined to help Bones stop a lethal magic from being unleashed, Cat`s about to learn the true meaning of bad blood. And the tricks she`s learned as a special agent won`t help her. She will need to fully embrace her vampire instincts in order to save herself—and Bones—from a fate worse than the grave.
