He's a vampire . . . a priest . . . and a slayer. A Sacrosancti brother of the Demetrius order. It's his calling to kill monsters-to efficiently dispatch them with his Crucilum and dispose of the bodies at Mercy Hill Crematorium. When Father Zaccaria wrenches Jane Maguire from the clutches of a blood thirsty monster about to sink its fangs into her throat, he's surprised to discover she's not the woman he's been tracking. She's her identical twin and the key to the Blue Blood's evil plot. Two women . . . sharing one soul. Can the priest protect his new charge and stop Andaes, nemesis of the church, from performing a mysterious blood ritual that will release the scourge of mankind from the confines of the night into the light of day to feast on the unwitting humans?
