War Party (The Sacketts, #8.5)

Bud Miles was a boy when he crossed the  Mississippi. But Bud buried his father after an Indian  attack, and as the wagon train pushed on through  Sioux country, the boy stood as tall as any man ...  Tell Sackett killed cougars at fourteen and fought a  war at fifteen. Now Tell was hauling dangerous  freight--a soldier's wife and a fortune in  gold--knowing that someone wanted him dead ... Laurie Bonnet  was a mail-order bride who thought she was a  failure on the frontier. But when the chips were down,  she was the only one who could save her husband's  life ... In these marvelous stories of the West,  Louis L'Amour tells of travelers, gunfighters,  homesteaders, and adventurers: men and women making  hard and sudden choices and fighting battles that  could cut a person's life short--or open up a bold  new future on the American frontier.
