This is not your ordinary YA book about angels. This is gritty, brutal, but also a very touching and well-written book. You have knights, bad angels, fighting, a dysfunctional family, and a young person finding their place in the world. The first time I read it, I'll admit I was shocked by it, but now I really appreicate it's uniqueness in the sea of YA novels. 
 Looking forward to book 2.
