Luna, El Caballito Negro - Daniel Guerra - Bog

Luna was a black little horse that had a birth mark on his head, white with a shape of a "half moon." Mark, Andrew and little Justin were horseback riding around their ranch when they found Luna, lost and very confused. Luna's family had been fallen into a trap that a "Juda" horse led them to it. Later on, Luna became a champion in the Kentucky Derby Horse Race.
