I love Rick's "Bill the Vampire" series,and while book is NOTHING like that, I still enjoyed it more than most other authors I read. His ability to switch styles is amazing. This book more like a MANGA novel. It has strong female lead characters, but is full of action and I was able to easily became entwined in the story and get caught up with the characters as if I were actually there. I found myself on a roller coaster ride of emotions. I think it might be okay as a Young Adult book, but it in NO WAY felt like I was reading a book meant for another age group. This is a great book and I cannot wait to the next one! Super smooth transitions, lovable and understandable characters, just a all a round wonderful read!!! ( I did receive an advanced copy to read, but that in NO WAY biased my opinion! This is a great book, and I plan on purchasing the next in the series.)
