A Reliable Wife

This book I saw at wal-mart and thought it looked good but I didn't buy it. I was with Brooke and she wanted a new book to read and I showed this one to her and she bought it. She absolutely hated it, hated the way it was written, everything about it. But she wanted me to read it and see what I thought. I couldn't put it down, it was not what I expected at all, a little strange, but mesmerizing.
I heard that this might be made into a movie, I hope so because i would love to see it!
