Adventures of Huckleberry Finn (or, in more recent editions, The 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 twenty years before the work was published, Adventures of Huckleberry Finn is an often scathing satire on entrenched attitudes, particularly racism.Huckleberry Finn is a boy about thirteen or fourteen. He has been brought up by his father, the town drunk, and has a hard time fitting into society. Tom Sawyer and his friends occasionally call him "Huck Finn".Samuel Langhorne Clemens better known by his pen name Mark Twain, was an American author and humorist. He wrote The Adventures of Tom Sawyer (1876)and its sequel, Adventures of Huckleberry Finn (1885), the latter often called "the Great American Novel."Twain's next major published work, Adventures of Huckleberry Finn, solidified him as a noteworthy American writer. Some have called it the first Great American Novel, and the book has become required reading in many schools throughout the United States. Huckleberry Finn was an offshoot from Tom Sawyer and had a more serious tone than its predecessor. The main premise behind Huckleberry Finn is the young boy's belief in the right thing to do though most believed that it was wrong. Four hundred manuscript pages of Huckleberry Finn were written in mid-1876, right after the publication of Tom Sawyer. Some accounts have Twain taking seven years off after his first burst of creativity, eventually finishing the book in 1883. Other accounts have Twain working on Huckleberry Finn in tandem with The Prince and the Pauper and other works in 1880 and other years. The last fifth of Huckleberry Finn is subject to much controversy.
