In 1851, Father Jean Marie Latour becomes the Apostolic Vicar to New Mexico. While the area is American by law, it’s still Mexican and Indian by custom and belief. During the years that follow, Latour tirelessly but gently spreads his faith while facing external and internal obstacles. Loosely based on the life of Jean-Baptiste Lamy and the construction of the Cathedral Basilica of St. Francis of Assisi, this novel chronicles the events that occur after the capture of the southwest by American forces during the Mexican-American war.
