In a spirited book, Camp grabs the notion of a child’s endless inquisitiveness and takes it for a quick spin. Lily, a little charmer that Ross has drawn as an explosion of red hair, drives her father crazy with her question. Why does the breakfast egg need one more minute? Why must they not forget to pick up garbage bags at the store? Why are there rain clouds? One day, just as her father shows signs that his limit has been exceeded, a giant Thargon spaceship appears at the playground and threatens to annihilate Earth. Lily poses a “Why?” or two, and the Thargons return home for the answers, leaving Earth intact. Lily’s questioning saves the day, but it’s no joke; the urge to understand, for her and children like her, is a survival instinct. (Picture book. 4-8)
