One of the masters of children’s picture books returns with a simple and lovely story about taking one’s time.    Teckentrup’s spacious, textured collages, brushed with soft color and populated by a pair of charming hedgehogs, convey the beauty of a natural setting, and the comforting bond between caregiver and child.   It is evening and the big and little hedgehog are slowly making their way home. There is so much to see, and the little one wants to take it all in.    Each step of the way the big hedgehog patiently asks, "What are we waiting for now?"    The little hedgehog’s answers unfold in a series of lush landscapes as the two animals wait for the sun to set, for birds to fly by, for the moon and stars to appear, and for the world around them to prepare for sleep.   At last, the little hedgehog is also asleep, carried home in the big hedgehog’s arms.    Perfect for naptime, bedtime—or for any time that asks that we take a moment and slow down—Teckentrup’s signature combination of simple text and soothing illustration will appeal to readers young and old.
