With clearly defined facts, irreverent humor, and a comics format, the titles in the Superheroes on a Medical Mission series offer accessible, entertaining introductions to health topics from sleep issues to HIV. Every volume stars a multicultural Super Friends like team of crusaders, each of whom introduces a different area of anatomy. Formatted in comic-style panels, the digitally generated images and dialogue-bubble text take a young person through a fantasy adventure, in which the team leads an interior body tour to learn about a particular health topic, including causes, treatments, and cures. Each title uses the format's possibilities for wordless communication to great effect. In Medikidz Explain Sleep Apnea, a clever series of images shows the characters tumbling down a throat in the wake of an upper-airway collapse. A glossary and resource lists conclude these informative introductions to high-interest health topics that kids may well read for fun, too.
