3.5. As much as I enjoyed reading this (and I flew through most of it over a single afternoon) I can't quite give it four stars. There were a few elements to the story that took it down a few pegs. On the positive side, this is a well paced mystery novel that had me hooked from the first chapter. It was very much the right book at the right time for me because there's something about YA mystery novels like this that I'm really loving at the moment. It is overall a really entertaining novel that I'm glad I picked up, and I would recommend. 
 On the negative side: although I didn't see the twist at the end coming, it didn't exactly blow me away either. It felt over-dramatic and I wasn't completely sold with the climax to the story. This was a four star read for me up until the last third of the book and then it went downhill a bit too quick. 
 Still, this was an enjoyable read and I'm glad I picked it up. The fact that I read most of it in a single day says a lot.
