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 complete depiction of one of the most significant moments in human history unfolds. Acclaimed journalist Chris Wallace does not settle for describing the bombings and the devastation they caused, but focuses on the controversies and hesitations of the political and military leadership, as well as the concerns of the scientists. At the same time, he illuminates the events from the perspective of those who played a key role in the decision-making and execution, while with immediacy and sensitivity he presents the lives of American and Japanese citizens during the war: from the "Calutron girls" in Oak Ridge, Tennessee, to ten-year-old Hideko Tamura who survives in Hiroshima but loses her mother and later emigrates to the USA, and the American soldiers fighting in the Pacific, waiting in fear for the order to invade Japan.     Reads like a thriller.
