I thoroughly enjoyed this mystery thriller. Sometimes I fell asleep (only because it was at the end of a long day). I would wake, flick back a chapter or two and try to work out where I was up to. I would have liked to more easily see the name of the narrator (when the topic and narrator changed). This would have enabled me to find my place a little more easily! I didn't want to sleep; I just wanted to know what was going to happen next!.
