I did not enjoy reading this. I'm not a fan of books that have heavy religious themes, and I know that's my bad for not reading the synopsis. It explicitly mentions fallen angels, Lucifer, and a second war on heaven. So I'll admit it's my own fault for reading this book and not liking it. 

However, my dislike of this story went beyond a strange and disgusting journey through the seven deadly sins. The pacing lacked rhythm, in my opinion. It would let the tension just dissipate half the time. I found myself bored more than once. Then, I would be horrified by what is happening or by what is casually mentioned on a consistent basis. Now, this may be the draw for some horror readers, but I found the whole thing to be revolting. 

If you liked this book, I think you would like Empire of the Vampire. It's similar, but better, in my opinion.
