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. The book was widely criticized upon release because of its extensive use of coarse language.
