Zoey Redbird has problems. Besides being a vampire, a favorite of the goddess Nyx, and the enemy of the head priestess, all of her friends hate her. All but Aphrodite, that is, and Aphrodite is hated by everyone else anyway. But weird things are happening. Aphrodite's prophetic visions are of Zoey dying, and invisible ravens are attacking Zoey in the dark. Soon she realizes that Kalona, a long buried evil being, might be rising again. Evil seems to be all around and Zoey may be the only one who can stop it.
