Hiroshima by John Hersey is generally considered appropriate for high school students, typically grades 9 through 12. The book, which first published in 1946, is based on the experiences of survivors from the atomic bombing of Hiroshima during World War II.
The level of complexity in both the language and the themes makes it suitable for mature readers who can engage with the emotional and historical weight of the subject matter. It’s often included in high school literature and history curriculums, providing students with insights into the human impacts of war and the ethical considerations of nuclear weapons.
While some younger readers might grasp essential themes, educators usually recommend it for older students who can appreciate the depth of the content and the historical context.
