The document summarizes key themes in the novel Heroes including heroism, appearance and reality, and forgiveness. Regarding heroism, the nature of true heroism is unclear as no character finds comfort in their heroism. War heroes are portrayed as inspirational figures through propaganda but are in reality victims unable to return to normal life. On appearance and reality, the townspeople see a sanitized version of war but the survivors bring back the harsh reality and cannot function normally. Characters like Francis and Larry hide their true selves behind masks.
