It's Perfectly Normal: Changing Bodies, Growing Up, Sex, and Sexual Health

In this intelligent, amiable and carefully researched book, Harris ( Before You Were Three ) frankly explains the physical, psychological, emotional and social changes that occur during puberty--and the implications of these changes. Taking a conversational, relaxed tone, Harris also discusses such subjects as sexual orientation, sexual reproduction, pregnancy, birth control, sexually transmitted diseases and sexual abuse. The author intentionally and effectively repeats certain crucial information, especially on the subject of the possible consequences of sexual intercourse. Alternately playful and realistic (and occasionally graphic), Emberley's ( Ruby ) watercolor-and-pencil art reinforces Harris's message that bodies come in all sizes, shapes and colors--and that each variation is ``perfectly normal.'' Cartoon panels illustrate various complicated processes (e.g., menstruation, the fertilization of an egg, childbirth). Appearing on each spread are two characters--an easy-going bird and an apprehensive bee--whose comments add levity to this solid volume. Ages 10-14. (Sept.)
