The Adventures of Tom Sawyer revolves around the youthful adventures of the novel's schoolboy protagonist, Thomas Sawyer, whose reputation precedes him for causing mischief and strife. Tom lives with his Aunt Polly, half-brother Sid, and cousin Mary in the quaint town of St. Petersburg, just off the shore of the Mississippi River. St. Petersburg is described as a typical small-town atmosphere where the Christian faith is predominant, the social network is close-knit, and familiarity resides.
