Just for girls

Girl in the Know: Your Inside-and-Out Guide to Growing Up
by Anne Katz, R.N., PhD. 

This book contains information about a girl's changing body, advice about communicating with family and friends, tips on dealing with cliques, peer pressure and bullying, and how to keep healthy through diet and fitness.

It's all very upbeat and self-affirming so that girls can become, in Katz's words, their be-you-tiful best. She tends to emphasize all the positives that come with growing up while fluffing over the negatives. And if girls encounter problems? Just talk to an adult, friend, doctor, or guidance counselor.

Breezily useful if not always helpful.
