While not being great literature, I felt it was a well written story with a wonderful theme of hope over adversity. This particular 13 yo has been seriously sexually abused in the past so sadly not unaware of the issues written about, and I think it would be a good book for her to read to address some of the issues she has going on, she's at the age where she will be processing her experiences in a new way in light of her own development and sexuality.
Anyway....is it appropriate for a 13yo at all? Esp one who has been abused? What do folk think? I'll ask her mum anyway and she might veto it but I thought I'd ask opinions before doing that.
