In both novels, Huck is portrayed as a lazy and adventurous boy who enjoys joining Tom Sawyer on escapades. At the conclusion of The Adventures of Tom Sawyer, he's adopted by Widow Douglas after saving her life. However, in Adventures of Huckleberry Finn, his adoptive mother tries to "civilize" him and make him more respectable. Despite this, Huck is kidnapped by his father but manages to fake his own death and escape with Jim, a slave owned by Widow Douglas' sister, Miss Watson. Jim runs away because he learns that Miss Watson plans to sell him for $800. The two embark on a journey down the Mississippi River in search of freedom from slavery for Jim and liberation from his abusive father and controlling guardian for Huck. The character of Huck Finn is based on Tom Blankenship, the son of an alcoholic who lived near the Mississippi River where Mark Twain grew up.
