Eight-year-old Leo thinks his grandparents are the most boring people on the planet—until he stumbles upon their “sewing room,” which is secretly a time-travel command center! Turns out, Grandma and Grandpa are part of a secret club of senior time travelers who keep history running smoothly. They’ve mended Cleopatra’s crown, stopped a dragon from eating the Great Wall of China, and even helped dinosaurs learn how to share a watering hole.

When one of their missions goes awry, Leo accidentally gets swept along to medieval times, where a cranky king has banned laughter. With his quick thinking, Grandma’s sass, and Grandpa’s endless supply of snacks, the trio must find a way to bring laughter back to the kingdom—and return home before history unravels completely.
