Query: A GRIPPING read!! A GREAT book!!

Before starting this book, make sure you have blocked off a big chunk of time to read it because if you set it down, all you will be able to think about is when you're going to be able to get back to it! From the first sentence through the clever plot twists to the great ending, it has you it in its control! Just a GREAT book!
