Pete is Eli's youngest son. He runs the McCullough Ranch in South Texas, where he and his wife, Sally, raise their three children. Unlike Eli, Pete believes in the social contract that people have the choice and capacity to treat each other with basic goodness. Pete loves his father, but sees Eli's dark view of humanity as antiquated and unnecessarily cynical. As regional violence lands on their doorstep, Pete is forced to defend his home, his family and his views about human nature. These experiences will push Pete into emotional and psychological depths, ultimately forcing him to make painful choices about his place in his own family.
