Publisher's Synopsis
Luna was a little black horse that had a birthmark on his head, white with a "half moon" shape. Mark, Andrew, and little Justin were riding on their ranch when they found Luna, lost and very confused. Luna's family had fallen into a trap that a "Juda" horse had brought her to it. A while later, Justin's father went to look for the little horse. Years later, Luna became a champion in the horse race of the Kentucky Derby.
