This book didn't grab me, but I think it may just be me and not the book. The author does a good job of delving into the mystery and setting things up. It presents lots of possibilities for the 'whodunit' and keeps you guessing, which is terrific. I had problems as the book wound closer to the ending, though. A few things seemed forced and so made the conclusion less satisfying for me. Others, though, may not feel the same way about how things wind up at the end, so, like I said, it may just be me. Also, the pacing, at times, was clunky, not to mention the writing. Many times I found myself rereading passages to be sure of the meaning. 
 I don't think there are tons of YA mysteries out there, so if you are a msytery fan, you may want to give this one a try and see what you think.
