In this true story, Collins joins up with a congenial group of Mexican riders retracing the pathways of Eusebio Francisco Kino, the pioneering Jesuit priest who explored the same borderlands three hundred years prior. The riders include a cross-section of Mexico's growing middle class, bonded by faith in the Catholic Church, love of family and their country, and dedicated to the cause of Kino's sainthood. They are also troubled by America's failed war on drugs and its outdated immigration policies, and they often wonder if the United States is their ally or adversary. Through their perspectives and insights, the reader comes away with a better understanding of borderland complexities and a difficult but workable road map for the future. With a passion for landscape, horses, and history, this modern-day cowboy adventure unfolds in the Sonoran Desert where the dangers are fewer than advertised, beauty far outweighs ugliness, and most people are still friendly and caring.
