The story is told from the viewpoints of three different, but variously connected, women. And what disasters the three of them are. I love flawed female characters. Either I can relate or they make me feel better about myself or give me insight into a type of life I wouldn't have otherwise given thought. I think it makes me softer and more forgiving. Here, there's the drunk, purposeless, cheated on, barren divorcee (Rachel), the former mistress turned stay-at-home mom (Anna), and the one who Rachel watches from the train and is neighbors with Anna.
