Query: Harrowing and disturbing

Not for the faint-of-heart, this book kept me up at night. Though I thought some of the scenes somewhat unbelievable, I can't honestly comment, having never been in prison. That said, I'd highly reconmmend this tale to anyone who likes a good story.Also recommended: Bark of the Dogwood, Fortune's Rock, The Five People you Meet in Heaven
