A good read. Given the subject matter it's not too tough or gruesome either (though it is a little, in places). It's more about what's happening in the minds of the two main characters. I thought the killer's pov was a little broad brush emotionally. It didn't particularly give me any startling new insights into what makes a person like that - but it was a good enough characterisation to make the story gripping.The boy's pov was more interesting as it showed the impact of his uncle's death on successive generations of his family. As a I-want-to-know-what-happens-next thriller it works really well. In particular I was waiting for the letters with as much anticipation as the characters I think.
