I read this book before letting my daughter read it just to preview the content and I must say it is an excellent, informational, yet fictional book for tweens and young teens. The main character, Margaret, endures troubles with a new school, friends, boys, religion, and other realistic things girls might worry about. There is some sexual behavior and suggestions including bra and period talk, use of the magazine Playboy, mild kissing, crushing, and rumors of dating. However, Margaret doesn't encourage this behavior and is cautious when it comes to her body and physical interaction with boys. Older girls can learn much about what's to come, their growing bodies, and what troubles or worries they might face through this fun fictional story.
