Mark Twain 
Tom Sawyer Abroad (Illustrated) 

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. It is a sequel, set in the time following the title story of the Tom Sawyer series.
