Sách nói: Buffalo Bill and the Overland Trail

Buffalo Bill Cody is one of the most colorful figures of the early American West. In these adventures we find Billy Cody at age 13 earning a man’s wage as an extra on a wagon train when he meets Davy, two years younger. Together they are in one adventure after another, fighting with Indians, and pressing on to Pike's Peak. They both prove themselves courageous in the face of danger as they ride side-by-side and grow into manhood. - Summary by Larry Wilson
