A gentle exploration of a child's thought: What would it like to be the biggest boy in the world? Billy is a big boy who can do all sorts of things by himself. And when his parents tell him he is growing bigger every day, he starts to imagine what it would be like to be the biggest boy in the world. “This collaboration of two award-winning book creators presents a favorite childhood theme—growing up. The bold, colorful, oversized illustrations add to the fun of the game played by Billy and his parents.” — The Horn Book
