Query: A great book for everyone

This book was one of the best I have ever read. I thought it was pretty boring at first but I kept reading. When you get to the end you will be amazed. I couldn't believe who the killer was and what he planned to do with his friend and her daughter. I didn't even know who Mary was until I was introduced to her. Ive read atleast 3 of her books in the past 3 months and they keep getting better. Mary is just the best.
