Adventures of Huckleberry Finn - Mark Twain
Tax included.
Huck is a young, naive white boy fleeing from his drunken, dangerous Pap, and Jim is a runaway slave longing to be reunited with his family. Flung together by circumstance, they journey down the Mississippi together on a log raft, each in search of his own definition of freedom.
Their daring adventures along the way provide both entertainment and a satirical look at the moral values of the Deep South of the 1800s.
