Gr 1-3-Fishman begins this work with an unbelievable but true statement about how there is enough energy in a person’s pinkie finger to power a large city for an entire day. From there the text segues into an exploration of energy, from the stamina it takes to read a book to running, and how our bodies recharge through eating, sleeping, and exercise. At the end of the book, there is an author’s note that explains how Einstein’s famous equation can be used to find exactly how much energy is inside a pinkie finger. Complete with colorful digital illustrations that highlight the learning points throughout the book, this is a great introduction to human physiology that affirms just how special our bodies are. The author manages to get across the basics without bogging down the text with too much technical language, making it accessible to younger readers interested in science. VERDICT A solid, upbeat ­addition to nonfiction shelves.—Jayna Ramsey, ­Douglas County Libraries in Parker, CO
