This book was a very quick read. I didn't realize that it was a middle grade book, because I picked it up from the library just based on the cover. There were things about this book that I enjoyed. The concept was interesting, as was the setting. I liked Serafina and her dad and their relationship. I also liked her friendship with Braeden, even though it seemed to materialize very quickly.

For me, the main issue comes with the mysteries, both the kidnappings and the mystery regarding Serafina's origins. I had her past figured out very early on in the reading of the book, and the other way before our protagonist. The 'foreshadowing' just wasn't subtle at all. And again, I understand that this was a middle grade book, but I think even a ten or eleven year old would see some of these revelations coming a mile away.

All that said, it was a very quick read, and kept my interest throughout. It looks as though this is going to be the first in a series, and I would probably pick the next up from the library if I saw it, but I wouldn't necessarily go out of my way to find a copy.
