I loved this book! I thought it was an interesting take on angels, and it was so hard to put down! 
 I liked Hand's angel mythology, which is slowly revealed over the course of the novel. She didn't take a particular side- it wasn't preachy, and it wasn't blasphemous. I thought the Dark Wings were interesting, and I want to know more about them, and their role in the rest of the series. 
 A lot of things were left open, and while a lot of things were resolved, I can't wait to read the next book. I also liked that Clara's purpose was slowly revealed, and that you're not entirely sure if it's been fulfilled properly and what the consequences will be. 
 I also liked the characters, but found that her mom was my least favorite. Her insistence that Clara figure everything out herself got really annoying by the end. But other than that, the characters were really interesting, and were developed really well. I connected with Clara and thought her journey was interesting, and yet realistic as she figured things. 
 What's so interesting about this book is that the angels weren't just there. They have a purpose, a reason for being there. There's nothing wrong with the paranormal-creature-0f the-month just being there, but it was refreshing to see angels with a purpose. 
 It gets a 5 out of 5. The pacing, characters, and mythology were well-written. The mythology was subtle and interesting. And I loved the setting and imagery! It was a great read.
