This beautifully illustrated wordless picture book tells the story of a young girl whose family moves into a new house. Outside, she can hear other kids playing, but sheâ€™s too shy to say hello. So she picks at the old wallpaper in her roomâ€”revealing an entryway to a fantastic imaginary adventure world behind the walls. There, she runs between the vibrant and varied environmentsâ€”surrounded by birds, swimming in a frog pond, in a herd of art-deco sheep. When it comes time to go back to reality, the girl feels inspired with the courage to approach the other kids and say hello.
