While I loved the first two books in the series, I have to admit I was a little disappointed by this entry. Saintcrow has a lovely feel of futuristic UF in her books & it reminds me of some of the old pulp books I'd find at thrift stores as a kid. This book just doesn't entirely capture the feel of the first two. I'll give a warning- there may be some spoilerish stuff in this review. 
 The third book finds Danny recovering from not only the psychic trauma from the previous case, but also doing some grieving over Jace. When Danny finds that Lucifer has been calling after her & wanting Danny to become his Right Hand as well as wanting her to hunt some escaped demons, some of the results cause Danny to seriously think about her current situation as well as her relationship with Japh. 
 This following part is sort of spoilerish. Ok. I can understand the problems in Danny & Japh's relationship. Neither of them know what it's like to be the other, so it's like two people trying to talk in two different languages & come to an agreement. So it's understandable that at some point they were due to have issues about what needs to be told & what doesn't. But did it have to be stretched out for so long in the book? Japh spends a good chunk of the book not telling Danny anything, even when things are trying to kill her. It's like "Oh, you have to hunt these 4 demons down & you're Lucifer's Right Hand for 7 years, but I'm going to lock you up for that time because of reasons I'm not really going to tell you, but rest assured that you're in lots of danger". A little of that is ok & perfectly understandable, but come on... after a while of reading it, it becomes a little repetitive. Danny just wasn't herself in this book. Even from the beginning of the book she was acting foolish. When you've got things chasing after you, trying to trick you & kill you, do you put on a bracelet that just magically appeared next to you on a ferry? Granted, the bracelet isn't doing anything bad to her, but come on... the Danny I know would've been a little more cautious about putting it on without any prior knowledge of what it could do to her. Assuming Japh sent it to you is a little out of character. In any case, too much time was spent on Danny being hurt & mistrusting Japh. After a while I just wanted to scream "Enough already! Move the plot forward!" 
 But even so, the book wasn't bad. It just seemed like it was a novella stretched out to book length. There's still promise, though. This book seemed to be a turning point for the series, so hopefully the next book will be a little better.
