Alan Gratz, bestselling author of Refugee, weaves a stunning array of voices and stories into an epic tale of teamwork in the face of tyranny — and how just one day can change the world.

June 6, 1944: The Nazis are terrorizing Europe on their evil quest to conquer the world. The only way to stop them? The biggest, most top-secret operation ever, with the Allied nations coming together — by land, sea, and air — to storm German-occupied France.

Welcome to D-Day.

Dee Carpenter, a young U.S. soldier, is on a boat racing toward the French coast. Dee — along with his brothers-in-arms — is terrified. He feels the weight of World War II on his shoulders.

But Dee is not alone. Behind enemy lines in France, a girl named Samira works as a spy, trying to sabotage the German army — and find her mother. At the same time, a paratrooper named James leaps from a plane to take part in a daring midnight raid. During the beach invasion, Henry, a medic, goes out into the bullets and bombs, searching for soldiers to save.

In a breathtaking race against time, each of them must fight to complete their high-stakes missions. But with betrayals and deadly risks at every turn, can the Allies do what it takes to win?
