These are the wild days when Gus McCrae and Woodrow Call - heroes of Lonesome Dove - first encounter the untamed frontier that will form their characters.Not yet twenty, Gus and Call enlist as Texas Rangers under the command of Caleb Cobb, a capricious outlaw determined to seize Santa Fe from the Mexicans. The two young men experience their first great adventure in the barren, empty landscape of the great plains, in which arbitrary violence is the only law - whether from nature, or from those whose territory they must cross in order to reach New Mexico.Danger, sacrifice and fear test Gus and Call to the limits of endurance, as they seek the strength and courage to survive against almost insurmountable odds in the West of early nineteenth-century America.
