A book for youngsters to learn the secrets hiding in a sheet of paper. It all begins with a cloud, that brings the rain, that waters the tree and makes it grow. The lumberjack cuts down the tree and in the factory the wood is cooked until it turns into paper pulp.
From Egypt to China by way of India and Japan, this was a secret kept under lock and key until... it got to Europe! A journey spanning many centuries that tells us the origin of books and paper.
