A little girl gallivants through a county fair, searching for her furry friend. Readers will surely spot the friendly monster as well as twenty shapes, identified here by their proper names—trapezoids, ellipses, kites, and more—hidden among iconic fair attractions from the fun house to the Ferris wheel. Maybe the monster is judging the pies? Or perhaps he’s at the monster-truck rally? Youngsters will be so mesmerized by Steve Light’s masterful pen-and-ink illustrations, decorated with vivid splashes of color, they won’t even realize they’ve learned how to spot a nonagon while looking for a monster.
