Query: Really not that good.

I almost always enjoy Jennifer Weiner's books, but I found this one to be slow paced. It is the story of Sylvie, a politician's wife, and their two daughters, Lizzie and Diana. Syvie has just discovered that her husband had an affair and she realizes that she has given up her entire self to look after him for all of those years. She leaves and tries to rebuild her life and her self-esteem. Her daughter, Diana, is a physician trapped in a loveless marriage and carrying on an affair with a resident at her hospital. Lizzie is the former addict trying to piece together her life and ends up in a situation she was not planning on.While the premise of the story is strong, I felt the characters development was not thoroughly hashed out, nor was the ending. I felt let down with this one.
