A New York Times Bestselling Author -- In the fall of 1873, a wagon train of immigrants sets off from Missouri for the Montana Territory. Leading them is wagon master Jamie Ian MacCallister, a giant of a man who swears he can get them there by Christmas. The journey is plagued by brutal storms and rugged terrain, outlaws and hostile Indians. Just when things look nearly hopeless, two unlikely saviors arrive: an old mountain man known as Preacher and legendary frontiersman Smoke Jensen.
