I thought this book was overall good. I did like that it was a fast read, and for the size it was a great novel. However, I think I personally would have liked it better had it been longer and fleshed out a little better. There aren't too many YA mysteries out there right now, so it was a quick refreshing read. I read a lot of adult mysteries, so I tend to figure things out rather quickly. But, I think this novel delivers on it nicely. I really enjoyed Clare, and her mouth :) The only thing that I didn't enjoy as much was that it was a little simplistic. And towards the end, the pieces seemed to just fall into place rather easily. A great debut novel. I will be checking out the sequels.
