Philippe Besson's novel essentially involves two Americans – Thomas Spencer (the narrator) and Paul Bruder – who were born on the same day: 6 August 1945, when the plane Enola Gay dropped its lethal cargo on Hiroshima. Thomas was born in Savannah, Georgia, although he never met his father, who left when his mother was pregnant, and who took her young baby to Natchez, Mississippi, where the Bruder family lived next door.
