Love my angel stories. I expected this one to have the angels as the main characters but being on the side of good. I was wrong. In this book, angels are predators. They feed off of human energy, causing humans to develop cancer, depression and many other illnesses. I'm not sure I really enjoyed this perspective of angels. The main characters, an angel killer named Alex and a half angel named Willow, are trying to stay alive and keep a second invasion of angels from crossing over. This book was an okay read, dragged in some places but had a lot of action. I liked the description of the angels in theory (until I learned they were "evil") and enjoyed the development of Alex and Willow's relationship.
