Mark Twain 
The Adventures of Huckleberry Finn [EPUB ebook] 

The Adventures of Huckleberry Finn is a picaresque tale of adventures on a raft on the Mississippi River. It begins with Huck Finn’s escape from his drunken, brutal father to the river, where he meets up with Jim, a runaway slave. The story of their journey downstream, with occasional forays into the society along the banks, is an American classic that captures the smells, rhythms, and sounds, the variety of dialects and the human activity of life on the great river.
'All modern American literature comes from one book by Mark Twain called 
Huckleberry Finn. There was nothing before. There has been nothing as good since.’
– Ernest Hemingway.
