The two major problems I have with this book (which is why I'm giving it 3.5 stars instead of 4):1) The random smattering of curse words. It's almost like the author felt like she needed to toughen up her material so she throws in a "fuck" every now and then. Every time one character told another character to "shut the fuck up" it brought me out of the story for a moment.2) Ari (the protagonist) and Sebastian (her main squeeze) fall for each other in like .05 seconds. I guess I just love UST so much that when the characters are literally slobbering and groping each other within 65 pages I start to lose interest in their relationship.Fortunately though, I really enjoyed the rest of the book. I don't think I've read a premise like this before, which is probably why I enjoyed it so much. There are tons of books on angels, and vamps, and werewolves, so this kind of story is like a breath of fresh air.
