The Tennessee town of Oak Ridge was created in 1942. One of the Manhattan Project's secret cities, it didn't appear on any maps until 1949, yet at the height of World War II it was using more electricity than New York City and was home to more than 75,000 people, many of them young women recruited from small towns across the South. Their jobs were shrouded in mystery. They knew something big was happening at Oak Ridge, but few could piece together the true nature of their work until the bomb "Little Boy" was dropped over Hiroshima. The shocking revelation: the residents of Oak Ridge were enriching uranium for the atomic bomb. Book jacket.
