There is no need for “a spoonful of sugar” to entice the whole family to read Dr. Howard Bennett’s latest book. The Fantastic Body: What Makes You Tick & How You Get Sick (Rodale, $19.99) is a handy and engaging reference guide to all the body’s organs and systems. Well-designed diagrams and features like tips for the next check-up provide essential information in a clear and comprehensible format; fun facts, DIY project instructions, and, yes, gross stories promise to keep young readers’ interest piqued with each turn of the page. Bennett brings 30 years of experience as a pediatrician and the lucid writing we have come to expect from his popular columns in The Washington Post to this masterful guide. Ages 6-12.
