Lonely on the Mountain — Louis L'Amour

The Sackett brothers didn't know what brand of trouble Cousin Logan was in, but he needed beef cattle badly. So with Tell Sackett ramrodding, Tyrel, Orrin, and Cap Rountree rode north--pushing 1100 head across the wide Dakota plains toward the mountains of far western Canada. Past Sioux, past Logan's treacherous enemies, through uncharted trails, the Sacketts drove on. Because when you step on the toes of one Sackett, they all come running.

The Sacketts, men and women who challenged the untamed wilderness with their dreams and their courage. From generation to generation they pushed ever westward, with a restless, wandering, urge, a kinship with the free, wild places, and fierce independence.
The Sacketts always stood - tall, and true to their strong family pride, they would unite to take on any and all challenges, no matter how overwhelming the odds.
