Commonly named among the Great American Novels, the work is among the first in major American literature to be written throughout in vernacular English, characterized by local color regionalism. It is told in the first person by Huckleberry "Huck" Finn, the narrator of two other Twain novels (Tom Sawyer Abroad and Tom Sawyer, Detective) and a friend of Tom Sawyer. It is a direct sequel to The Adventures of Tom Sawyer. The book is noted for its colorful description of people and places along the Mississippi River. Set in a Southern antebellum society that had ceased to exist about 20 years before the work was published, Adventures of Huckleberry Finn is an often scathing satire on entrenched attitudes, particularly racism.
