I had some mixed feelings about this story. The very well developed characters and mystery of the story kept me reading. I wanted to know what happened to Abby. Was she really gone? Did someone kill her? Was it an accident? Is she still alive and just exacting revenge on her sister? I needed to know! But then the ending happened and I learned nothing. I was mad. I didn't understand how the author could leave me hanging like that, but then I realized her genius. This story is so well written that it feels real. The characters and situation could happen in real life and so she couldn't give me a neaty wrapped ending with all the answers, because that's not what happens in real life. Nicely done, Rachele Alpine!
