The newest addition to the 2 million copy-bestselling "What's Happening to My Body?" series, written especially for boys ages 8 and up.

Recognizing a need for puberty education books for younger children, award-winning author Lynda Madaras published Ready, Set, Grow!: A "What's Happening to My Body?" Book for Younger Girls in 2003 to widespread acclaim. Now, in her uniquely straightforward, warm, and funny style, Madaras introduces On Your Mark, Get Set, Grow!: A "What's Happening to My Body?" Book for Younger Boys .

Responding to real-life questions and concerns from younger boys about their changing bodies, Madaras covers a wide range of topics at a reading and understanding level that's just right for them: the growth of sex organs, body hair, and facial hair; weight and height spurts; the unwelcome appearance of acne and body odor; shaving; circumcision; erections and ejaculation; feelings about puberty; and bullying.

Illustrated throughout with lively two-color drawings, On Your Mark, Get Set, Grow! is the newest entry in the popular "What's Happening to My Body?" series that has influenced an entire generation of readers. The "What's Happening to My Body?" books for older boys and girls are on the American Library Association's "Best Books for Young Adults" list and have been translated into 12 languages.
