Madeline seems like a decent person and so does Jonny. They are friends first which was really nice in a romance. In fact, we really see more of their friendship than of the romance. It's a quiet story (surprising since Jonny's a star. Didn't know that? Oh, well it's mentioned. A lot. So is how surprised he is not to be treated like a star. We're almost bludgeoned over the head with it.)
I may have liked this book a little more if "Thrill Me" hadn't hit such a sweet spot for me but I'm not sure. And, as always, shoehorning in past characters was just painful.
