A friendship blossoms between two children as they pass drawings across the clothesline between their apartment windows in this imaginative picture book about creativity, the power of art, adventure, innovation, and friendship.

Between two windows, Kayla and Mateo pass drawings of dinosaurs back and forth, back and forth, back and forth... until a story comes to life and the worlds of two friends come together.

But when the clothesline is taken down, the friends must use their creativity to find a new way to keep their story going.
