Ruby the Red Runner is a children's picture book that introduces how oxygen travels through the human body. Set in Vitalia, a magical town inside the body, readers follow Ruby, a red blood cell carrying a glowing parcel of oxygen along the Pulse Paths. As Ruby travels through different parts of Vitalia, children discover how the lungs, heart, muscles, stomach and brain work together, while learning about the important role of red blood cells in delivering oxygen throughout the body.
