When the war of the ancients had taken more lives on the battlefield than remained, Chiron, leader of the Centaurs, climbed to the top of the hill and commanded the battle to stop. Banishing the half-horse, half-man creatures from the Greek world, he then turned and made one last proclamation before he, too, disappeared into the heavens. "We will leave," he said, "but we take with us the hearts of your best women and through them we will rule your world for all eternity." Why do women love horses? Was the Centaur's Promise real? Cynthia Szantos is lost in a dead-end job and a failing romance, when a rider-less black horse bolts onto a Southern California freeway and Cynthia's life takes an unexpected twist. She begins to dream about a Centaur who explains to her the accident was an opportunity to rediscover her talents and use then to help save America's wild horses. Together with a vet and a Navajo code talker she learns how the mystical power of the horse can create a spiritual and physical connection to the universe that modern man has long ago forgotten.
