It's already late August, but Billy Whee isn't nearly ready for the summer to end. He'd do almost anything for a few more summer evenings catching fireflies with his friends. So as Billy lay in his bed, gazing up at the last full moon of the season, he has a crazy idea. What if he could capture the moon and keep it as his prisoner? Could he bring out a full moon whenever he wanted one? Billy can't believe what happens next, as he reaches out his window, firmly grabs hold of the moon, and begins to pull. These impossible happenings bring hilarious and improbable results in this eloquently written story about a boy's dreams and secrets.
