This book is awesome. However, it is really creepy. Patch as a character is scary and dangerous, and seems to have an unhealthy interest in Nora. Throughout the story, he becomes endearing, even lovable, but the mystery of who he really is and what he will do is always there. The book contains a lot of Biblical knowledge about the fallen angels of Genesis, and their half-human descendents, the Nephilim. Nora is trying to figure out how everything fits into the equation when her life is threatened from all sides. You are kept guessing about who the "good guys" and "bad guys" really are until the very end. This book is great for fantasy and supernatural fans.
