I think it was good. It was just kind of average I guess. 
 But there is a few things I'm wondering: 
 (view spoiler)[Wouldn't she have wondered a long time ago and asked if Phoenix was an angel of dark? I know I would've (hide spoiler)] 
 and I think this whole "Grigori partners cannot be together in that way" thing is completely stupid. I mean, these people are expected to heal each other and work alongside each other for...centuries. And their not allowed to be together IF romantic feelings shall develop. That's sort of a fail right there. 
 Also, why would Phoenix sleep with Violet, being able to read her emotions, and know she's thinking of Lincoln. WHO DOES THAT? That whole scene in the book just sort of annoyed me. 
 I think it wasn't great and it wasn't bad. The writing style was good, and even though there was this FREAKING love triangle that dominated most of the book and all of Violet's reasoning, I'll give it 2.5 stars
