Tim O'Brien is an American novelist known for writing about his experiences in the Vietnam War. His writings focus on the abstract psychological effects of war on soldiers, depicting characters without heroism or family lives. By drawing on dialogue and vivid descriptions of warfare, O'Brien's works seek to make readers feel as though they are part of the depicted platoons. While some of his novels do not explicitly focus on the Vietnam War, there is often an undercurrent related to the events and atmosphere of the time period. O'Brien continues to teach and write today, still influenced by his experiences in the war.
