With their harrowing journey across the Great Plains now successfully behind them, Sam and Jay begin building and defending The Bartlett in the savage Comanche lands of what is now, southeastern Colorado. Their rewards are all they had hoped for as the Bartletts carve out a successful horse-ranching endeavor that they hope and pray will someday be instrumental in settling the vast lands of not only the Arkansas Valley, but the entire southwestern United States, as well. Through hard work and steadfast determination, the ranch flourishes while they raise their son, Tom, to manhood. Along the way, he meets the love of his life, Sue Hobbs. However, none of this comes without costs as Tom loses a number of the things that are dear to him, including his faith in the Lord.
