Alex Grosjean, Oracle to the gods, is back. A tall, dark and pointy-toothed stranger shows up at Alex's door and asks for her help: he wants to find Lamia, an insane monster-woman who cursed him and turned him into a vrykolakas. Alex doesn't want to take the case, but after a plague sweeps through the city and Lamia starts abducting children, she finds she doesn't have a choice. As usual, the gods task Alex with stopping both the plague and Lamia, but don't offer much help. Even Alex's boyfriend, Harry, has a dark side and secrets of his own. After a trip across the world and a frightening encounter with the goddess Hekate, Alex must push herself to her very limits to save not only herself, but the world. Again.
