A Huffington Post Best Children's Book of the Year

From Pulitzer Prize winner Jane Smiley and Caldecott Honor artist Lauren Castillo.

As her mom reads a bedtime story, Lucy drifts off. But later, she awakens in a dark, still room, and everything looks mysterious. How will she ever get back to sleep?

Pulitzer Prize winner Jane Smiley's first picture book, illustrated by Caldecott Honor artist Lauren Castillo, evokes the splashy fun of the beach and the quietude of a moonlit night, with twenty yawns sprinkled in for children to discover and count.
