2.5 stars. Interesting take on angels and demons, but I didn't really love anything about it. The characters were okay, nothing spectacular. I thought Anna was a bit cardboard, even though she's supposed to be so perfect. Kaiden has potential to be swoony, but the scenes where he is real with Anna are few and far between. It ended with closure, sort of. I can see where the story would go for the other two books, but I'm not sure I'll be reading them.
