Bell, a longtime teacher, taps a deep well of imagination, carrying young readers to silly, kid-pleasing places. Williams-Ng, contributes a whimsical style that compliments and elevates the text. A few of the illustrations, the cover choice in particular, shine in their showcase of the artist’s skill. Delightfully ridiculous.
