On April 12, 1945, Roosevelt dies. Harry Truman, who succeeds him, is unaware of the existence of the Manhattan Project for the construction of the first atomic bomb. With the pace of a spy thriller, the most comprehensive depiction of one of the most important moments in human history unfolds. Esteemed journalist Chris Wallace goes beyond describing the bombings and the devastation they caused, focusing on the conflicts and concerns of political and military leadership, as well as the reflections of scientists. At the same time, he sheds light on the events from the perspective of those who played a leading role in making and executing the relevant decision, while presenting the lives of American and Japanese citizens during the war with immediacy and sensitivity: from the "Calutron girls" in Oak Ridge, Tennessee, to ten-year-old Hideko Tamura, who survives in Hiroshima but loses her mother and later immigrates to the United States, and the American soldiers fighting in the Pacific, anxiously awaiting the order to invade Japan.
