"Inspired by a verse of A. Vvedensky," a lovely litany of queries and subtly modulated responses: "Are the wolves asleep? Asleep...And the birds? Asleep, asleep...And the children? All asleep...Only you and the wind are awake. And the wind sings, 'Sleep, sleep. You too, you too....' " Tafuri visualizes the drowsing world in luscious muted tones defined in crisp pen lines varied with gently feathered edges. Quintessentially simple and altogether beguiling: a perfect choice for tuck-in time. (Picture book. 1-6)
