Well, to take the Ebert approach, in which one judges each work on what it tries to achieve, then this is a full-on 5 star book, and that's what I'm rating it. OK, it's not great literature, but it doesn't try to be, and that's ok. This was one of the best reads I've ever had. I almost literally couldn't put it down. I was guessing to the end, and the characters were fairly believable. Granted this is a subject about which I know little, so a more knowledgeable reader might quibble with its verisimilitude, but as far as I'm concerned, it convinced me. Sometimes ignorance is bliss, know what I mean?
