The Adventures of Tom Sawyer by Mark Twain is an 1876 novel about a young boy growing up along the Mississippi River. The story is set in the Town of "St. Petersburg", inspired by Hannibal, Missouri, where Twain lived. Tom Sawyer's best friends include Joe Harper and Huckleberry Finn. In The Adventures of Tom Sawyer, Tom's infatuation with classmate Rebecca "Becky" Thatcher is apparent. He lives with his half brother Sid, his cousin Mary, and his stern Aunt Polly in the (fictional) town of St. Petersburg, Missouri. In addition, he has another aunt, Sally Phelps, who lives considerably farther down the Mississippi River, in the town of Pikesville. Tom is the son of Aunt Polly's dead sister.
