Query: Great First Book

I am really loving the novels that involve demons. It is a great break from vampires and werewolves. This is one of the better paranormal books I have gotten my hands on. Not only does it involve demons, but whole new subclasses of humans in a complex and very detailed world. It made for a very entertaining story.It took on a new view of the religious side, if you can call it that. It mixes quite a few Gods from different parts of the world. It was interesting. I love reading about something other than the common crucifix storyline. I look forward to reading more from both series and author.
