"The new life they find in New Mexico is not what the Pate and Lewis families hoped for. Driven by disagreements with their father, eldest sons Richard and Melvin abandon the Pate family to join eastbound freighters on the Santa Fe Trail, an antidote that provides no relief. Younger brother Abel works with his father to build a ranching empire atop the Pajarito Plateau, while the Lewis family establishes a thriving mercantile network in Santa Fe and outlying communities. The families you met in Father unto Many Sons return in This Thy Brother as they face the challenges of poverty, discrimination, war, graft, rustlers, romance, and the harsh realities of life in the desert Southwest. Together, the families work for prosperity while the departed sons turn toward a different future. Will a tenuous foothold in a new land hold firm? Can the broken families survive? Will-can-the prodigal sons return? Seek answers to these and other questions in the pages of This Thy Brother"-- Provided by publisher.
