SO GOOD! 
 I haven't read a good dystopian angel book in awhile and this was like a dose of fresh air. A completely new take on this genre as well. 
 "I never thought about it before, but I'm proud to be human. We're ever so flawed. We're frail, confused, violent, and we struggle with so many issues. But all in all, I'm proud to be a Daughter of Man." 
 Hell has broken loose on Earth and angels are not our saviors as we would expect them to be. Penryn is trying to escape the city with her mother and sister (who is bound to a wheelchair) when they come across Angels fighting in the street. Penryn feels compelled to save one angel who seems to be getting bullied - Raffe - only for another angel to fly away with her sister. This sets Pen on a mission to save her sister, but in order for Raffe to help her she has to help him get his wings back. I love that Pen was so capable of doing everything on her own and protecting Raffe just as much as he protected her. They made an epic pair together in this California gone to hell. 
 (view spoiler)[ When we find Paige finally she's been turned into a human demon zombie thing! Sketch. As well as Raphael's wings have been switched during surgery by Laylah (knew she was bad news) from white archangel to black archdemon wings that not even his own sword trusts. Him following Pen thinking she's dead at the end broke my heart to see them separated. (hide spoiler)]
