This was ok, I think I enjoyed it more than the first. I liked some parts of the book but it did drag in places. The problem I had with it was that I've finished and the situation is still roughly the same as it was at the end of the first book. Nothing's really been resolved. Or has even progressed that much. Oh and this p*ssed me off to the extreme -- (view spoiler)[How come Beck sleeps with some reporter (and doesn't make a secret out of it may I add) but when Riley sleeps with some Fallen Angel it's a mega deal and storms out. Double standards much? Even with Beck's POV, he still confuses me. He drops occasional "secretly Riley is the most important person in my life" hints but then doesn't think about her much, doesn't do much for her and wasn't there for her when she was having problems. He sleeps around but then wants Riley's virginity himself because we all know that was what he was upset about not that she's "betrayed the Guild" or some other BS. 
 Although it was glaringly obvious she was being played by Ori (and I'll be the first to admit that she acts like an idiot most of the book), cut her some slack! She's 17 years old, he has wings and is basically as old as time itself, and she's expected to resist something like that? What's Becks excuse then? (hide spoiler)] Having said all that, I am intrigued with where this is all going. I hope both Riley and Beck get a grip and sort out their lives. It'd be cool to see them work together more, trapping demons and all that (I think only one was trapped in the whole book) and getting closer that way, keeping things on the micro scale instead of all the war-and-end-of-days talk because I do find the world and the different levels of demons interesting, more than the angel stuff. 
 ETA: If you're not sure whether to read it or not, then just read it and ignore me lol since there are loads of people who love this series :)
