Dessen writes about female teenage "issues." I have enjoyed several of her other books greatly. So far Keeping the Moon is my favorite.
This book didn't engage me as much as her others. (I still played hookey from doing academic work for a few hours to finish reading.) I think it may be because I just didn't follow how the main character fell into an abusive relationship. Physically abusive relationships are, thank goodness, outside of my experience. I don't have a good sense of how a relationship ends up at this level. Perhaps if I did more research I would understand. As it is I just didn't "buy" the central conflict.
Caitlin's older sister has also left the home and broken with the family. The portrait of the mother's involvement in all this was also unconvincing. As I was reading I thought there must be a back story--but all the mom's interactions seemed pretty loving and somewhat open for direction from her daughters.
I'm interested. If you have read this let me know how you felt about it.
Probably good for older middle school/early high school girls.
