Reader Request

Can you help out? Reader Lisa sent the following note and I'm somewhat stumped. If you have a recommendation, please drop me an email or post a comment. Thanks!

I'm trying to find a good book about puberty (don't need sex info, mostly about body changes and such) from a Catholic/Christian perspective for my almost ten year old. I did pick up the American Girl book on this topic, but would like to have something besides a secular resource. Any suggestions? Several people have recommended Beyond the Birds and the Bees for my husband and I to read, as it's geared for parents, but I'm looking for something for my daughter (and I guess for my son before I know it, as he is about to turn 8!) Thanks so much.
