Was only just a bit above lukewarm for reading this as i read it this week ... but after the final page i went, "Whoa..."
Glad I read it.
Think of the movie "Ordinary People" and couple that in with legal stuff and a murder trial, a clever change in tense here and there, and ongoing grand jury testimony (written in the book in typewritter script) sprinkled throughout the book...
It happened for me. I'd give it a very solid 7 on the 10 scale. Nothing fancy schmancy but cleanly written and a story most surprising. And there you go!
