 I loved, loved, loved this book. It was so fun and creepy. Anna was amazing in her "goddess" form, and I loved Cas. His voice was excellently done. Many times when a female author writes a male MC he doesn't quite sound male. Cas does, and I love it! 
 This type of book is right up my alley. Supernatural is my favorite show and this book is very reminiscent of that. I enjoyed every single page of this book, and if there's a sequel I will be waiting on pins and needles for it!
