I'm a huge Grisham fan, but this one didn't do it for me. There was no escalating tension typical of the rest of his thrillers, and my mind wandered repeatedly. It almost seems like a huge set-up for a second book, because what we'd really like to see happen--the protagonist take some action--doesn't. Not until the end is she finally poised to do so. That being said, I like the main character, and I'd like to see her in another book. Additionally, this is a great expose of the world of coal-mining. Pretty eye-opening stuff, and that alone makes it worth consideration.
