Children's ✦ Penny’s Take
The Real Science of Superspeed and Superstrength
Christina Hill · 2022
74/100
👍 Worth It
Lerner's Alternator Books series knows its audience well — reluctant elementary readers who light up when science connects to superheroes — and this 32-page entry on biomechanics, exoskeletons, and athletic performance delivers on that promise. The magazine-style layout, Spanish-language edition, and Epic platform availability all signal a book designed for broad classroom reach. Necessarily introductory at 32 pages, but that is exactly right for the age.
