I thoroughly enjoyed the first 1/3rd of this book. I loved reading about the character and both how he felt and how he fought those feelings. There were many similarities to the character of Dexter in Jeff Lindsay's series, but I was able to overlook them. However, in the remainder of the book, it took a more supernatural, unrealistic turn which I DID NOT like and could not overlook. I kept waiting for main character to realize that this was all in his head, something he made up as a way to play into his darker urges, but I was disappointed. Overall, I am left disappointed that the author felt the need to fall back on the supernatural rather than to write about the very real demons in the world today.
