The Winter Fortress

From the internationally acclaimed, best-selling author of Hunting Eichmann and The Perfect Mile, an epic adventure and spy story about the greatest act of sabotage in all of World War II.
 
It’s 1942 and the Nazis are racing to be the first to build a weapon unlike any known before. They have the physicists, they have the uranium, and now all their plans depend on amassing a single ingredient: heavy water, which is produced in Norway’s Vemork, the lone plant in all the world that makes this rare substance. Under threat of death, Vemork’s engineers push production into overdrive.
 
For the Allies, the plant must be destroyed. But how would they reach the castle fortress set on a precipitous gorge in one of the coldest, most inhospitable places on Earth?
 
Based on a trove of top secret documents and never-before-seen diaries and letters of the saboteurs, The Winter Fortress is an arresting chronicle of a brilliant scientist, a band of spies on skies, perilous survival in the wild, sacrifice for one’s country, Gestapo manhunts, soul-crushing setbacks, and a last-minute operation that would end any chance Hitler could obtain the atomic bomb—and alter the course of the war.
