Stone is a wall the size of a world. Through the cracks in Stone's mighty wall emerge creatures from all the ages of life on Earth. In this strange vertical realm, where the clouds tumble downwards and the greatest peril is to fall, Jonah Lightfoot and Annie West come face to face with dryads and dragons, a forest that talks, a globe-shaped ship. Ancient myth and the magic by which our world was once ruled are alive still on Stone . . . and the magic is just beginning. Archan the immortal red dragon - forever evil - is on her way back to Stone from the abyss into which she was cast.
