I think this was a case of me reading the right book at the right time. The plot itself really appealed to me. 
 The look at how to deal with being bi-polar as a teen was very interesting. I hadn't known everything that the condition entails - in fact for whatever reason I had a very different image of it. The guilt that's eating the heroine apart as well as the fear of slipping back into the bad days is constantly at the surface of everything. Mixed in with this is a haunting. 
 At times the story dragged a little. I didn't like the new friends: they all remained very shallow and weren't likeable. The romance at times was also a little shallow, or at least it sped up very quickly. The story itself was a slow-burning and it's not until beyond the 50% mark that the thriller part of it becomes more evident. The ending left a lot of threads still open... 
 However, the story was very atmospheric. The style was engaging and kept my interest the whole way through. I wanted to read instead of sleep (but unfortunately that wasn't possible). The thriller aspect had me wrapped around its little finger. I wanted more of the story and when I read that ending I couldn't believe that was the actual ending. Again, it left me with my heart in my throat as I longed for more that I knew would never come.
