The book is funny. When Huck recounts the episode where he and Tom both separately concoct plans to free Jim and then compare them, I laughed out loud. The deadpan humor Mark Twain uses in Huck's character is often very good.
I also enjoy the themes of this novel dealing with the conflict between Huck's "natural conscience" and his "learned conscience". This conflict is, perhaps, what truly makes this book timeless.
Ernest Hemingway wrote, "All modern American literature comes from one book by Mark Twain called The Adventures of Mark Twain. Twain's insight into human nature is phenomenal, his satire of American society both biting and witty, and thoroughly amusing as a simple boy like Huck understands more than the "civilized." Twain masterfully points to the hypocrisy and foibles of Americans in a narrative rich with colloquial flavor that captures the setting. It is a narrative that takes the reader, not just down a river, but into the heart of what makes the land of the United States.
The Adventures of Mark Twain is a narrative that has long delighted many a boy and girl; but it is also an insightful indictment of the hypocrisy of American society. Twain's work can be read on many levels. A great classic of American literature!
Mark Twain's The Adventures of Huckleberry Finn may seem a bit old fashioned to many new readers not familiar with mid-19th century life in rural America. But this novel has few comparisons when it comes to its mix of adventure, comedy, satire and social commentary. (Most of the same can be said of the earlier Twain companion piece, The Adventures of Tom Sawyer.) Huck's adventures are virtually non-stop, and Twain's colloquial language and dialogue were groundsbreaking when the novel was published. Huck's journey down the river is a quest for independence and adventure that most boys can only dream about. His discoveries about the people that he meets along the way are not lost on this poor, uneducated boy, and his own growth and understanding about the world around him are just some of the pleasures of reading this book.
Are you asking about the whole book? If so...
The main thing I find interesting about this book is the general story. Whatever it is supposed to mean, it is an exciting book in a lot of places. It is exciting to see what Huck goes through as he tries to escape from civilization and his father. It is exciting to see things like what happens with the feuding families. It's just a good story. It can also be quite funny at times. Twain is a great writer who is very good at making funny little quips and observations.
To people who are more serious about literature, there are a lot of other things that are interesting. They like to talk about the tension between Huck's conscience and the values of society. They like to talk about how Twain satirizes pre-Civil War Southern values.
That stuff is there, but the book is also just interesting to read.
