The third book in this fun series has Nick realizing that he really is a demon. As the last Malachi, his powers should not have unlocked till after his father's death but because of his own interference from the future things have changed dramatically. Nick is doing his best to stay a good man but the evil that is his demon side is fighting him.
Once more a fast read that drags you from start to finish. I found that reading the first three book in a day was a rip roaring fun trip that leaves you wanting more. Now not everyone reads as fast as I do, but starting up an establish series gives you other books to dive into as soon as you finish up the last.
