I'd like to point out that this book by far has the most typos then any of the books. That isn't necessarily a terrible thing but after six books I expect the quality of writing to get better not worse. That being said I did really enjoy this plot more then the others. Dr. Green is quickly becoming my favorite of the nine. He's quirky and sweet and has Sang's best interest in mind whenever he's around. 
 Volot finally made an appearance. I've heard of his from the Academy website and was curious as to his motives. I have a pretty good idea of who it is but I'll keep that to myself. This book was also the longest in my opinion. I'm not sure if page-wise it is but multiple times in this story I felt the book could just end and I would be happy. But then something else happens and they all run off on a wild goose chase yet again. 
 Sang's vicious side finally got let loose in this book as well. When the others are incapacitated she doesn't hesitate to jump in and rescue then which I adore. She's finally breaking out of her shell and I'm happy to say, doesn't blush so much in this book.
