Query: An excellent book

I am a big fan of John Grisham. I have read all of his books. I will agree that some are better than others. I think that this one is one of his best. I think too many people are comparing it to The Firm, though. It is a different kind of story, and until you accept that you probably won't like it. It has its slow moments, but it's all worth it in the end.
