The Dukes, their children: Nephilim, and the world of demons sent by Hell to tempt humans is interesting. I liked that there was more than the seven sins to include drugs and alcohol. I really liked all the characters except Anna. I mean she is great, but I found her character to be lacking flaws and I found her to be a bit whiny. However, towards the end of the book, Anna grows some balls and grows up a little so she‘s starting to grow on me.
