Inside a mysterious house, a glorious adventure unfolds, as picture-book grandmaster and three-time Caldecott Medalist David Wiesner presents an inventive and exquisitely illustrated tale of community, wonder, and coming together to make a difference.

At Hilbert House, new worlds await behind every closed door and ordinary chores turn into extraordinary adventures—changing lightbulbs becomes fixing an anglerfish’s glow; moving the furniture becomes emotionally engaging a wardrobe; these and more slyly humorous subversions of a seemingly mundane to-do list will delight readers. The residents of this remarkable boarding house come in all shapes and sizes, each relishing the unique atmosphere of their own private room. But when a crisis in Room 239 brings everyone together to help a stranger, what starts as a problem may turn out to be the best thing to ever happen to this remarkable community.

Packed with details and endlessly imaginative, Room 239 is a tour-de-force from bestselling author/illustrator David Weisner, one of only two artists to ever win three Caldecott Medals. Celebrated worldwide for his boundary-breaking picture books and unique visual storytelling, he has also received three Caldecott Honors and was a finalist for the Hans Christian Anderson Award, the highest international recognition bestowed on a children’s book creator.
