I read "Hearts in Darkness" and enjoyed it. I thought of it many timesa after having read it. I wasn't sure what to expect with a follow-up. I did enjoy revisiting Caden and Makenna. So much of this story was mired in Caden's depression, though. It wasn't a very happy story. It did have a happy ending, but I don't feel confident about what will happen the next time Caden has an episode.
