The Girl's Body Book: Everything You Need to Know for Growing Up by Kelli Dunham

From chapters.ca:
Fun to read and easy to carry, it answers all the important questions about becoming a woman that girls are sometimes too embarrassed to ask. From hygiene to exercise, teachers to peer pressure, everything's discussed here, in a frank and friendly way: parents that drive you crazy, boys who’ve caught your eye, best friends, physical changes and menstruation, schools and grades, body image and proper nutrition, and moodiness and other emotional stuff. Sections on high school, part-time jobs, and even career planning will feed a girl’s dreams of the future.

While it is an excellent book on growing up, it does not address any issues that are particularly controversial. A good clean book for parents looking for something that does not talk too much about sex, but it will not answer any hard-hitting questions. For that, try the Little Black Book for Girlz or something similar.

The Little Black Book for Girlz: A Book on Healthy Sexuality by the St. Stephen's Community House

Preface:
No matter what age we are, many of us prefer to speak to our peers about experiences we are going through, especially around issues of sex and sexuality. Many young women have expressed to us that there is a lack of material they can relate to on sexuality and relationships. They want something no only aimed at them, but also created by them. Out of this frustration came The Little Black Book for Girlz. The book was created by young women who hung out at the St. Stephen's Community House Youth Arcade Drop-In, in downtown Toronto. As a group we had many discussions about all kinds of different issues. These discussions were very honest and non-judgemental, and the girls wanted sex ed. material that was equally positive and empowering to them. As a group we decided to write our own book that would encourage other young women to learn more about their bodies, their relationship, and their lives.
