Koko Kondo was 8 months old when the atomic bomb was dropped on Hiroshima. As she grew, she struggled to come to terms with the bomb's legacy, and with being a hibakusha, or survivor. While still a teenager, she fled Hiroshima and eventually moved to the US, where she hoped to marry. But when her engagement was called off due to radiation fears, Koko returned to Japan. She then made it her life's mission to share her experiences with people from all walks of life, to pass on the torch of peace.
