Castle’s Little Zeb (Gorgeous, not reviewed) romps his way through another adventure in a rambunctious tale about not sleeping. In a classic scenario, Big Zeb tucks Little Zeb in for the night but Little Zeb has other ideas. Like an impish toddler, Little Zeb gleefully throws off his covers and prances about. Even a few last-minute games with his parent fail to tucker out the little tike. Creeping out of his bed, Little Zeb discovers a playmate in fellow bedtime truant Little Hippo, and together they splash and play until their parents return. What’s a weary parent to do? Put the two to bed together, of course, but this mischievous duo has a surprise ending in store for readers. Castle’s tale is perfect for toddlers, who will immediately empathize with Little Zeb and his antics. Childs’s cheery illustrations capture the spirit of this fun-loving tale; Little Zeb is roguishly charming and disarmingly adorable at the same time. Brightly hued landscapes create a striking contrast to the black and white zebra figures, providing readers with dynamic, stimulating illustrations. While not precisely conducive to a peaceful transition to slumber, Castle and Childs pack a whole lot of fun into one oversized book. A playful tale to share with tots at bedtime or beyond.
