I have over 300 books in my library. I am now coming back to this book to grade it after listening to the last one. This is by far one of the best series I have ever listened to, and I cannot believe I put it on my wish list for over two years. The artwork was making me hesitant to spend a credit on it, but if you were somebody that likes the consistent on the edge of your seat feeling this is the book for you I really really hope the author decides to give us level nine. The concept this author ran with was brilliant and if I could give this 10 stars, I would.
