Adventures of Huckleberry Finn takes place on the Missouri section of the Mississippi River, in 1835-1845. The book was published in 1884, and Twain said the events in the novel occurred 40-50 years before the book was published.
The town where Huck and Tom live is called "St. Petersburg", but is based on Hannibal Missouri.
Here are the characters:
Huckleberry Finn: Roughly 14 years old, illiterate, impoverished, and all but orphaned. Through recent adventures, has come into a large amount of money, which leads his virtually absent father to reappear, in hopes of cashing in on the windfall. Huck is a natural prevaricator, and uses a variety of names throughout the novel: Sarah Mary Williams, George Jackson, Alexander James Hopkins, George Peters....
Tom Sawyer: Huck's friend, and possessor of a huge and romantically adventurous imagination.
Judge Thathcher: Becky Thatcher's father (see the book Tom Sawyer), and trustee for Huck's money.
