Originally created by KidsHealth.org, The Pink Locker Society is now a book series and website for girls 8 to 12. The novels were written for curious girls who have questions about what it means to grow up.

Read chapter 1 of the first book, Only Girls Allowed.

Readers will find info about body changes and development woven into the action, which centers on three best friends, Jemma, Kate, and Piper. But The Pink Locker Society is more than just a basic guide to puberty. The books cheer girls on as they approach the emotional ups and downs that go along with being a "tween-ager!"
