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, that they won't even realize they've learned how to spot a nonagon while looking for a monster.
