I received an ARC copy. 
 I'm giving this a whole extra star based solely on the fact that the whole idea of this angel mythology is refreshing. In a YA market filled with sub-par angel novels, this one does stand out to me. 
 This is a big book and it starts off well. However, towards the middle it comes to a halt and gets overly mushy and gooey. While some will enjoy this, I found it to be rather cheesy and it stalled the action in the book. 
 Another aspect in this book is the narration. Told in first person from Willow, then third person from Alex. While I'm not sure if I liked this or not, it was confusing. It did take some time getting used to the writing style. It felt forced. 
 Overall, I did enjoy the book, but it does get predictable and overly mushy. So while I may read the sequel, I won't be rushing for it. There are quite a few questions left to be answered.
