In July 1881, Lt. A.W. Greely and his crew of 24 scientists and explorers were bound for the last region unmarked on global maps: Farthest North. What would follow was one of the most extraordinary and terrible voyages ever made, as Greely and his men confronted vicious wolves, sub-zero temperatures, and months of total darkness. As Buddy Levy recounts here, the ship became trapped, and now new dangers awaited: insanity, threats of mutiny, and cannibalism. Greely considered a desperate plan for survival, while back home, his equally intrepid wife worked tirelessly against government resistance to rally a rescue mission.
