In Ride the Dark Trail, Louis L'Amour tells the story of Logan Sackett, a cynical drifter who changes his ways to help a widow keep her land.
Logan Sackett was wild and rootless, riding west in search of easy living. Then he met Emily Talon, a fiery old widow who was even wilder than he was. Tall and lean, Em was determined to defend herself against the jealous locals who were trying to take her home. Logan didn't want to get involved--until he found out that Em had been born a Sackett. Em was bucking overwhelming odds, but Logan wouldn't let her stand alone. For even the rebellious drifter knew that part of being a Sackett was backing up your family when they needed you.
