I liked this book, particularly Marci's character.
I was really disappointed that Marci died. She seemed much more interesting and a better match for John than Brooke ever was. Marci felt like a person whereas Brooke has always felt more like a fantasy.
John's relationship with his mother seemed pretty typical, all things considered. He's a teenager so even if he was perfectly normal there would probably be some amount of distancing. Wells did a good job with that.
I'm somewhat concerned about the direction the series is going in. I think it could be interesting to see how John functions without his mom but I'm less interested in this new group he's become a part of and Brooke has never been that interesting to me.
