"Blood and Feathers" was not my kind of book. It containes a level of weirdness (giant teeth!) that did not work for me. From time to time little weird extras can make a book more fascinating, but this time it just made it hard for me to enjoy the story. Plus the whole Heaven v. Hell thing played a bigger part in the book than I was hoping for. I don't know why, but reading about angels is something I often don't enjoy.
To make it short: This book was not for me!
