It's 1886, and Chicago is booming, but for nineteen-year-old Torsten Pilkvist, American-born son of Swedish immigrants, it's not big enough. After tragically losing a rare love, Tory immerses himself in the pages of a Wild West mail-order bride magazine, where he stumbles on the advertisement of frontiersman and Civil War veteran Franklin Ausmus. Torsten and Franklin begin an innocent correspondence-or as innocent as it can be, considering Torsten keeps his true gender hidden. But when his parents discover the letters, Tory is forced out on his own. With nowhere else to go, he boards a train for the Black Hills and Franklin's homestead, Moonlight Gulch.
Franklin figures Tory for a drifter, but he's lonely after ten years of living in the backcountry alone, and his "girl" in Chicago has mysteriously stopped writing, so he hires Tory on as his ranch hand. Franklin and Tory grow closer while defending the land from outlaws who want the untapped gold in Franklin's creek, but then Franklin learns Tory's true identity and banishes Tory from his sight. Will their lives be forever tattered, or will Torsten-overhearing a desperate last-ditch scheme to snatch Franklin's gold-be able to save Moonlight Gulch and his final shot at love?
