Adventures of Huckleberry Finn is a novel by Mark Twain, first published in the United Kingdom in December 1884 and in the United States in February 1885. 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, a friend of Tom Sawyer and narrator of two other Twain novels (Tom Sawyer Abroad and Tom Sawyer, Detective). 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. Perennially popular with readers, Adventures of Huckleberry Finn has also been the continued object of study by literary critics since its publication. It was criticized upon release because of its coarse language and became even more controversial in the 20th century because of its perceived use of racial stereotypes and because of its frequent use of the racial slur "nigger", despite arguments that the protagonist and the tenor of the book are anti-racist. The story begins in fictional St. Petersburg, Missouri (based on the actual town of Hannibal, Missouri), on the shore of the Mississippi River "forty to fifty years ago" (the novel having been published in 1884). Huckleberry "Huck" Finn (the protagonist and first-person narrator) and his friend, Thomas "Tom" Sawyer, have each come into a considerable sum of money as a result of their earlier adventures (detailed in The Adventures of Tom Sawyer). Huck explains how he is placed under the guardianship of the Widow Douglas, who, together with her stringent sister, Miss Watson, are attempting to "sivilize" him and teach him religion. Finding civilized life confining, his spirits are raised somewhat when Tom Sawyer helps him to escape one night past Miss Watson's slave Jim, to meet up with Tom's gang of self-proclaimed "robbers." Just as the gang's activities begin to bore Huck, he is suddenly interrupted by the reappearance of his shiftless father, "Pap", an abusive alcoholic. Knowing that Pap would only spend the money on alcohol, Huck is successful in preventing Pap from acquiring his fortune; however, Pap kidnaps Huck and leaves town with him.
