"The Legal Limit" by Martin Clark. Can't put it down.

[Lex]

Well, a word of advice. Don't start this book "The Legal Limit unless you have blocked off large spaces of time in your day. It's ten minutes to 4 a.m. and I can't stop reading this book! It's fascinating. I just got up to make myself a PBJ and a glass of milk hoping that would make me sleepy enough to put the book down. It doesn't help that 1. it's based on actual events that happened, 2. it's very well written, 3. true events really are more compelling than fiction (it is a fictionalized account of true events), and 4. it is set in Stuart, Va. in Patrick County where I've visited many times so some of the references to places are familiar.
