Lonely on the mountain

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.
