True to His Word — K. Sue Morgan

With her father dead and the Union Army occupying Vicksburg, Elizabeth Benedict had to grow up quickly. Determined to hold onto her family home until her brother Jonathan returned from the war, she was stunned when long, tall Texan Jake Travers arrived with the news that her beloved sibling was dead -- and that he had vowed to take care of her.
With the war over, all Jake wanted was to return to his peaceful life in Austin. Dragging an unwilling female away from her Mississippi plantation wasn't something he looked forward to. Yet he soon discovered that keeping lovely Elizabeth by his side was much more than a debt of honor ... and that the promise he longed to hear her give was, "I do."
