In Lonely on the Mountain, Louis L’Amour’s solitary wandering Sackett brothers make a stand together—to save one of their own.

The rare letters Tell Sackett received always had trouble inside. And the terse note from his cousin Logan is no exception. Logan faces starvation or a hanging if Tell can’t drive a herd of cattle from Kansas to British Columbia before winter. To get to Logan, he must brave prairie fires, buffalo stampedes, and Sioux war parties. But worse trouble waits, for a mysterious enemy shadows Sackett’s every move across the Dakotas and the Canadian Rockies. Tell Sackett has never abandoned another Sackett in need. He will bring aid to Logan—or die trying.
