Parents of Tweens (9-14) discussion

I was wondering if anyone has read this book? I downloaded it on my Kindle by accident, and now my 8 year old daughter is reading it, but I thought that I better get some feedback from this group. Is it ok for her? If it is ok, then heads up, it is a free download on Kindle. Thanks!

I've heard of it only because one of my GR peeps is reading it I think. Do let us know how she gets on. Do you record her reading on GR? I try to do Thomas's but I neglect it sometimes.
