In this sweetly humorous book, Stella and her brother Sam take a night walk to explore the wonders of the sky. The vast, luminous heavens, the stars, and the rising moon form the backdrop for their nocturnal expedition. As Stella and Sam encounter raccoons, fireflies, tree frogs, and bats, Sam wonders if the moon can swim, if the sun wears pajamas, and if he can catch shooting stars with his butterfly net. Stella, as always, has an answer for every question. Marie-Louise Gay"s whimsical prose and enchanting illustrations capture the joys of young children making their first discoveries of the world around them.
