Query: Weak Characters, Weak Romance

I was really disappointed with this book and had trouble finishing. After I read all of the 5-star reviews I was expecting so much more. The main character, Robert, came off as weak and cowardly whereas his wife was like a doormat for most of the book. It's a shame since the storyline had a lot of promise in the beginning.
