Answer: Hiroshima by John Hersey is nonfiction.
Hersey’s book, published in 1946, is a poignant account of the experiences of six survivors of the atomic bombing of Hiroshima during World War II. The narrative is based on real events and highlights the devastating impact of the bomb on individuals and the city itself. Hersey used journalistic techniques to tell the stories of these survivors, providing an unfiltered look at the human cost of war. Rather than creating fictional characters or events, he meticulously reported the accounts of real people, making Hiroshima a powerful work of nonfiction that serves both as historical documentation and a compelling narrative.
