Book excerpt: Here is a beautiful and unique picture book in turn-around format about the concept of day and night. Open the book, and the sun rises to reveal blue skies, crowded barnyards, and bustling streets. Turn the book over, and the moon comes up to the hush of night with its bright stars, hooting owls, and sleeping children. Young audiences will delight in the experience of going from morning to night -- and back again -- in this stunning creation from the Caldecott Honor -- winning author-artist of Have You Seen My Duckling?
