In this magical bedtime story, the lyrical narrative echoes a Runaway Bunny like cadence: Does everything in the world go to sleep? the little girl asks. In sincere and imaginative dialogue between a not-at-all sleepy child and understanding parents, the little girl decides in a cocoon of sheets, a nest of blankets, she is ready to sleep, warm and strong, just like a tiger. The Caldecott Honor artist Pamela Zagarenski’s rich, luminous mixed-media paintings effervesce with odd, charming details that nonsleepy children could examine for hours. A rare gem.
