Girls Will Be Girls: Raising Confident and Courageous Daughters by Joann Deak (published 2003)
If you have a daughter coming up to the "tween" phase or in the tween phase (ages 8-12), this is a book for you as it helps explain all the things girls are going through and offers ideas on how to parent through these new waters.
For me the book is worth it for just for the section on girl friendships and how exploring those relationships. It discusses cliques, fitting in and how some girls use "camouflaging" as a way to protect themselves while they go through what can be an awkward stage of development.
The goal is help your daughter not lose her self or her voice in the process of this change.
Anyway, I read the book in just a few evenings and actually enjoyed it with its examples and shorter sections written in a very easy to read and digest style.
Highly recommend for anyone with a daughter between 8-12 or read this before your daughter becomes a tween! Probably a better way to go!
