The locals called it a "Comanche moon". It was when the moon was full and put out such a light in the dead of night that no man, woman, or child was safe in their beds. The Comanche warriors swept through Texas in raids that brought death, and if you were lucky, or rather not so lucky, it brought slavery of the worst kind. Luke Jones is hired by the renown Texas Rangers to redeem recent Comanche captives. He never expects one of the women, Catherine Swann, to refuse to go with him, and he certainly never expects to fall in love with this fiery woman of God, who believes it her mission to bring salvation to the warlike Comanche. He fully plans to rescue her whether she wants him to or not.
