The novel's preeminence derives from its wonderfully imaginative re-creation of boyhood adventures along the Mississippi River, its inspired characterization, the author's remarkable ear for dialogue, and the book's understated development of serious underlying themes: "natural" man versus "civilized" society, the evils of slavery, the innate value and dignity of human beings, and other topics. Most of all, Huckleberry Finn is a wonderful story, filled with high adventure and unforgettable characters.
