The chapters alternate the individual perspectives which show how one experience can affect each person differently. There are many different characters, but the author manages to keep the perspectives clear and separate.
Like others who've read this novel, I found the first half to be slow. I came close to putting it down several times and not picking it up again. But, there was a compelling element that made me want to continue reading and find out the truth of Lila and Billy's story. The story picks up towards the end as truth is realized.
I honestly can't say that I liked the book. It isn't an uplifting book by any means. However, it is one that could stay with you which, depending on your own personal life experiences, will either be good or bad. One of the things I did enjoy was the use of literature. Lila was an English professor and both she and Billy not only loved books, but books were an integral part of their lives and their relationship.
