In this deceptively simple wordless picture book, a small girl finds the end of a long black line and picks it up. She wiggles the line, slides down it and spins inside circles made from it. In her hands, the line transforms into bubbles to blow, a jungle vine to swing from and a tightrope to balance on. The girl is having such a good time! Until suddenly, the line turns into a big, hungry monster! Oh, no! Will the little girl be eaten, or will another surprise twist to the line save her from the frightening creature? Young children will become instantly involved in this story, curious to see what's next for the magical line that is transformed again and again, and delighted by the surprise on the last page, where the drawer of the line is revealed.
