As Huck and Jim drift down the river, they meet many colorful characters and have many great adventures. The true heart of the story, however, is the friendship between Huck and Jim. A constant theme throughout the book is Huck's internal struggle between what he has been taught, that helping a runaway slave is a sin, and what he truly believes, that Jim is a good man and it couldn't possibly be wrong to help him.

Adventures of Huckleberry Finn was unique at the time of its publication (1884) because it is narrated by Huck himself and is written in the numerous dialects common in the area and time in which the book is set. Although the book was originally intended as a sequel to the children's book The Adventures of Tom Sawyer, as Twain wrote Adventures of Huckleberry Finn it progressed into a more serious work. Twain's views on slavery and other social issues of the time become clear through the words, thoughts, and actions of Huck Finn. The book has always been the subject of great controversy, and according to The American Library Association it was fifth on the list of most frequently challenged books in the 1990s.
