Dal and Mac Traven fought on opposite sides of the Civil War but rode home together to start rebuilding the family ranch. Instead, they discovered the chilling aftermath of a guerrilla rampage of terror. It was said no force in Texas could stop these raiders on their bloody path to Mexico. But now the raiders had the Travens' sister and Dal's girlfriend, Kate Connery, held captive. Now they had the Travens on their trail and even though it would be just Mac and Dal and their brother Jesse and Uncle Jack against thirty killers, the Travens would keep on coming. For as Kate Connery kept telling the other women hostages, "The Travens will never stop until we are free or they are dead."
Del and Mac Travers fought on opposite sides of the Civil War, but were brothers as well as friends. When they got back to TX it was to find it was changed and their sister and fiance had been kidnapped to be sold into slavery in Mexico. Book is old and worn, but readable and I think it's one of Louis' best stories.
