A United States Air Force pilot is shot down over Siberia in the Soviet Union during the 1980s and held prisoner at a remote camp, but soon escapes into an even greater prison -- the vast, harsh landscape. However, because he is a native Sioux Indian with survival knowledge he learned as a boy, Major Joe Mack must use all his hunting, trapping and evasion skills to escape his pursuers, especially a ruthless Yakut who follows him. Considered one of L'Amour's best novels, this classic story of adventure is richly textured, deftly plotted and riveting to the end.
