(3) 4-6 Superpower Field Guide series. Illustrated by Nicholas John Frith. Teeth, tails, and building are just some of the beaver's "superpowers" according to this breezy, conversational guide, which covers beavers' anatomy, eating habits, habitat, and why they were once endangered. The retro aesthetic and familiar animal subject may not grab kids right away, but if they start reading, they'll soon be hooked by the ample humor in both the text and cartoon illustrations. Reading list, websites. Glos.
