"Propulsive." --Time * "Reads like a tense thriller." --The Washington Post * "The most exciting book I've read all year." --Admiral William H. McRaven From Chris Wallace, the veteran journalist and anchor of Fox News Sunday, comes an electrifying behind-the-scenes account of the 116 days leading up to the American attack on Hiroshima. April 12, 1945: After years of bloody conflict in Europe and the Pacific, America is stunned by news of President Franklin D. Roosevelt's death. In an instant, Vice President Harry Truman, who has been kept out of war planning and knows nothing of the top-secret Manhattan Project to develop the world's first atomic bomb, must assume command of a nation at war on multiple continents--and confront one of the most consequential decisions in history.

But Countdown 1945 is more than a book about the atomic bomb. It's also an unforgettable account of the lives of ordinary American and Japanese civilians in wartime--from "Calutron Girls" like Ruth Sisson in Oak Ridge, Tennessee, to ten-year-old Hiroshima resident Hideko Tamura, who survives the blast at ground zero but loses her mother and later immigrates to the United States, where she lives to this day--as well as American soldiers fighting in the Pacific, waiting in fear for the order to l
