This is a good book and an exciting read. The story is well told with decent characterization and you feel you get to know the characters as the book progresses. And the plot makes sense as well, although the motivation for the villain is never explained convincingly. So that's all good, so why only four stars? Simple. It's the back story. The protagonist is saddled with one of the most stupid and irritating families I've ever encountered in fiction. His wife needs to wake up and smell the coffee, and the children are just terminally annoying. If they were my family, I'd probably have shot the lot by now. My other problem is the climax of the book which just seemed both wholly predictable and extremely unlikely, as if the protagonist had suddenly lost all reasoning ability and was completely unable to see what was manifestly obvious to everybody else, and certainly to the reader. But having said all that, I did enjoy it, and I might well read another novel by the same author.
