I've been a Greg Iles fan for years, and after reading Natchez Burning and The Bone Tree, was eagerly awaiting the final book of the trilogy.
Did it live up to expectations? Oh, yes, that and so much more. As one reviewer stated after giving it five out of five stars, "I'd give it ten if I could."
I didn't read it in one sitting - it's 692 intense pages - but I was unable to get anything else accomplished until I had finished the final page.
