Thirty thousand years ago, an imaginative child sees the shapes of animals in clouds and on the walls of the cave he shares with his family, but no one else can see them until he makes the world's first drawing. Includes author's note on cave drawings.

When a young American woman, who works at a London auction house, receives a 17,000-year-old fragment of a cave painting from a British soldier, she sets out to find the fragment's true origins.
