A disappointing second book by the author of Before I Go To Sleep. The main character makes so many bad choices, and blaming it all on grief isn't convincing enough to make her decisions feel at all real or likely. I'm not a prude, but the looooong sections of the book focusing on the character's obsession with an online hook-up and her venture into a seedy affair were just so unappealing to me. The mystery of her sister's death gets dropped for big chunks of the narrative as we read more and more about Julia's sex life. The tension finally picks up in the second half of the book, making it hard to look away -- but the resolution is so awful and ambiguous that it made me regret the time I'd put into it.
