This was a good mystery thriller, following a family that gradually drift further and further apart as they get entangled with a new family until the ultimate dramatic accident occurs that brings everything to a head. The book dips back and forth in time, gradually unravelling more of the mystery until it comes to the conclusion. The only thing I didn’t like about it is that all the way through I couldn’t see how it tied in with the prologue… and it turns out that prologue chapter was a dream. A bit annoying. But it’s a good mystery, trying to guess what’s happening and why, and very interesting when it’s all revealed.
