Novelists like Henry James, Joseph Conrad, and Virginia Woolf explored hidden realities and psychological depths. They used techniques like stream of consciousness to represent complex inner thoughts. Modern novels dealt with a wide range of themes influenced by science and war. They presented life in realistic, and sometimes pessimistic, ways. The fragmented structures of novels reflected the disintegration of society.
