It was not inevitable that World War II would end as it did, or that it would even end well. 1944 was a year that could have stymied the Allies and cemented Hitler's waning power. Instead, it saved those democracies -- but with a fateful cost. 1944 witnessed a series of titanic events: FDR at the pinnacle of his wartime leadership as well as his reelection, the planning of Operation Overlord with Churchill and Stalin, the unprecedented D-Day invasion and the horrific Battle of the Bulge, and the tumultuous conferences that finally shaped the coming peace. But on the way, millions of more lives were still at stake as President Roosevelt was exposed to mounting evidence of the most grotesque crime in history, the Final Solution. Just as the Allies were landing in Normandy, the Nazis were accelerating the killing of European Jews. Winik shows how escalating pressures fell on Roosevelt, whose rapidly deteriorating health was a closely guarded secret. Was winning the war the best way to rescue the Jews? Was a rescue even possible? Or would it get in the way of defeating Hitler? In a year when even the most audacious undertakings were within the world's reach, including the liberation of Europe, one challenge -- saving Europe's Jews -- seemed to remain beyond Roosevelt's grasp.
