I think this is my second favorite Gillian Flynn book. I was ok with Sharp Objects, loved Gone Girl, and this fits nicely in the middle of the two. And I didn't figure out who did the murders, although some in the book group picked up on the clues. I loved how much I really didn't like the main character, who was honest to the point of saying there is no way she could ever have a Monday-Friday job because that would require her to actually work. That's self awareness! There's some rated R parts, but for the most part the story was intriguing, and it kind of makes me glad to be kind of a boring person rather than the girl whose family was murdered. It was a dark book. Take only in small doses (I may have needed some anti-depressants as I read it).
