Prior to the attack on Pearl Harbor, America had long been involved in a shadow war. Throughout 1941, President Roosevelt concocted ingenious ways to come to Winston Churchill's aid, without breaking the Neutrality Acts. Conducting espionage at home and in South America to root out Nazi sympathizers, and waging undeclared war in the Atlantic, were just some of the tactics with which America battled Hitler in the shadows.

President Roosevelt also had to contend with growing isolationism and anti-Semitism as he tried to influence public opinion. While Americans were sympathetic to those being crushed under Axis power, they were unwilling to enter a foreign war. Wortman tells the story through the eyes of the powerful as well as ordinary citizens. Their stories weave throughout the intricate tapestry of events that unfold during the crucial year of 1941.
