This was a very good, enjoyable read. I liked both, Denver and Adam, very much. Although I'm unfamiliar with OCD (I know what it is, but I don't know anyone with it), I had the impression that what Adam felt and the difficulties he dealt with every day where described rather realistic. The slowly developing relationship, the understanding Denver showed, all that was very engaging to follow. Add to that Denver's problems and this could have been a very dreary read. Thankfully that wasn't the case. In the end we came full circle and again in a very fitting way, as it was not picture perfect, but instead a believable show of growth, how far Adam came during the course of the book.
Oh - and I especially liked Louisa and I hope, we will see more of her.
