Huck's father has heard of his son's good fortune. So he forcibly takes his son and locks him in a cabin. I'm not certain if Huck's Pap is a drunk, psychotic or both. Whichever one of them it is, he becomes violent and Huck starts to fear for his life. He fakes his own death, escapes and meets up with runaway slave Jim. Jim is trying to make his way to a free state where he will buy back his families freedom. That's when the adventure really begins.
Like I said before, it was difficult to get into. But once I got into, I really enjoyed it. Give it a try, let me know what you think :)
