In the fourth book, THE MESSENGERS - Three strange beings appear foretelling messages of the future and revealing secrets of the past to Matt, Brittany, Angelo and Shekinah. Far away from their safe surroundings they are drawn into dramatic searches for centuries old treasures. Together they come face to face with their most dangerous challenges. Shekinah, now a noticeable strong and beautiful stallion, begins his mission. Shekinah starts to speak to the other horses on the Gaudino ranch trying to convince them to ride with him when Jesus returns. Many horses remain skeptical until Shekinah reveals to them his true white color. Following that, many of the horses are convinced he really is 'The Lord of the Horses' as foretold by their ancestors, and they agree to follow him. There is, however, one drawback. Not all are convinced.
