Zoey has lost three boyfriends and her friends. Stevie Rae is alive, but has strange red tattoos. Book four picks up after Loren and Prof. Nolan's death. Erik comes back after his full change to teach drama. Aphrodite has visions of Zoey's death and her friends finally find out why she was keeping so many secrets. Add to that Nefereet's plans to unleash a mythical angel, ready to pillage the earth.
Once again, really enjoyed this book. Although Zoey's tattoos spreading at the end of each book is a little redundant.
