"For sheer adventure L'Amour is in top form."—Kirkus Reviews

Here is the kind of authentically detailed epic novel that has become Louis L'Amour's hallmark. It is the compelling story of U.S. Air Force Major Joe Mack, a man born out of time. When his experimental aircraft is forced down in Russia and he escapes a Soviet prison camp, he must call upon the ancient skills of his Indian forebears to survive the vast Siberian wilderness. Only one route lies open to Mack: the path of his ancestors, overland to the Bering Strait and across the sea to America. But in pursuit is a legendary tracker, the Yakut native Alekhin, who knows every square foot of the icy frontier—and who knows that to trap his quarry he must think like a Sioux.
