I enjoyed this story very much - and what a well-constructed ending! All three main characters were well developed, and I was not bored or repulsed by any one of them, which is often the case with a book split into various perspectives. As these women experience the psychological stresses that come with the story's gnarly moral dilemmas, the author Liane Moriarty does a thorough job of allowing the reader to know the psychological intricacies of what they are thinking and feeling.
Within the bounds of what the novel sets out to achieve, it succeeds brilliantly. CBS has bought the rights to the book, and it's going to make a terrific TV movie.
