Mo Willems, #1 New York Times bestselling, award-winning author-illustrator, tackles a BIG concept in this hilarious non-fiction picture book about the relationship between size and scale.

Are YOU big?

A simple question sends readers to the far reaches of the universe. From an average-size kid . . . to a hot air balloon . . . to a storm cloud . . . to the M100 Galaxy, size is a matter of perspective.

Bold text, expressive art, and real-world science come together in this original Mo Willems STEAM-based, early-learning concept book.
