Starts out incredibly promising as a fantasy. Setting up some background information about angels and demons and the fallen. There's also a fun Western element that unfortunately falls off not too far into the story. It seems like a book that was uncertain of what genre wanted to inhabit. I don't mind a hybrid so long as it's done well. 

This book actually ended up being more of a noir murder mystery with our main character, Celeste, attempting to figure out who murdered a man that people seem to think her own sister killed. 

This book was largely about Celeste and how she navigates her relationships (not well). In the beginning I found her insanely likable, by the end, I'm not so certain where I stand with her. It's not necessarily a bad thing. It's just how things work out sometimes. 

Also, the ending scene where her demon boyfriend tells her that he doesn't want her anymore and that he deserves better was unintentionally kind of funny? Like picture that scene in the South Park movie where Satan and Osama are in bed together and Satan's trying to get Osama to connect emotionally with him. That's the read I'm getting of that scene. Comedy gold really
