On 6 August 1945 the US army, by order of President Harry S. Truman, dropped an atomic bomb on Hiroshima. The bomb, nicknamed 'Little Boy', killed somewhere between 90,000 and 170,000 people. It was the first nuclear weapon used against human beings; the bomb dropped on Nagasaki three days later was the last.
Kinue Tomoyasu was a 44-year-old widow at the time of the bombing. Her son had left to fight in the war and she lived with her only daughter. The transcription included in the book is somewhat edited.
