“Huckleberry Finn” is considered Twain’s greatest novel because the issues are more serious, like Huck’s abusive father, a runaway slave, Jim, and Southern prejudices in the mid-1800s. Most of the raw material from the book came from Twain’s own boyhood in Hannibal, Missouri. Anyone who hasn’t read “Huck Finn” is missing one of the greatest American novels, which is both exciting and humorous. A personal note: at age 11, my father took me to Hannibal, Missouri, to see where Twain grew up and see the great Mississippi River. At age 15, he took me to Elmira, New York, to see Twain’s grave. My other favorite Twain novel is “The Adventures of Tom Sawyer.”
