“An amazing organ presented with amazing clarity.”
—Kirkus Reviews (starred review)

“A buoyant shout out to the body’s most important organ, rewarding reading for lower elementary children with a serious interest in their own anatomy.”
—School Library Journal

“The artwork, “created with digital tools,” is more sensitive and appealing than most digital drawings, and the portrayal of children playing soccer will attract kids’ attention while certain concepts are demonstrated. Other books on the brain are available, but few have so many large, helpful illustrations of children enjoying all the activities that their brains allow them to do.”
