This Caldecott Medal–winning picture book gets children ready for bed with rhythmic text and glowing illustrations that explore the warmth and light that makes us feel at home. "Here is the key to the house." Inside the house are nighttime things both comforting and intriguing—a bed, many books—and outside, too, there are sources of light and joy—the moon, the sky—that reveal a reassuring order in the universe. This timeless bedtime tale takes readers through the house in the night, up into the sky, and back home again, all the while reminding us of the presence of love and wonder in our world. Susan Marie Swanson’s spare verse and Beth Kromme’s astonishing illustrations intertwine to create a comforting, magical story to revisit again and again.
