Tom Sawyer Abroad by Huck Finn

Tom Sawyer Abroad is a novel by Mark Twain published in 1894. It features Tom Sawyer and Huckleberry Finn in a parody of Jules Verne-esque adventure stories. In the story, Tom, Huck, and Jim set sail to Africa in a futuristic hot air balloon, where they survive encounters with lions, robbers, and fleas to see some of the world's greatest wonders, including the Pyramids and the Sphinx. Like Adventures of Huckleberry Finn and Tom Sawyer, Detective, the story is told using the first-person narrative voice of Huck Finn. (Summary by Wikipedia)
