The Adventures of Huckleberry Finn starts out with a brief description of the previous book, The Adventures of Tom Sawyer. Both boys stole twelve thousand dollars in the previous book; each boy got six thousand a piece. Huck Finn and Tom Sawyer are both young boys growing up before the Civil War along the Mississippi. Both boys are mischievous but Tom is the one with all the plans, he reads a lot which gives him these ideas, which are fairly eccentric. Huck Finn does not live with either his mother or his father, in fact he seems to fear his father which he refers to as pap', he lives with a widow who takes care of him and makes him act very proper. It is thought that Huck's pap is dead but Huck believes that he is alive and will come get him eventually.
The first adventure that Huck has is with Tom Sawyer and a group of other young boys who band together to form a robber gang, all under the influence of Tom Sawyer. Their mission is to rob people and then kill them, however none of this ever happens and the gang soon breaks up.
Shortly after the gang splits, Huck's evil father comes back and takes him away from the widow. Pap takes Huck into the woods and makes desperate attempts to get the six thousand dollars which Huck owns. Luckily however, Huck gave it the bank manager, Mr. Thatcher for safe keeping. The beatings that Huck's father gives him become unbearable, so Huck finally decides to run away. However, he does not merely jump in a raft and float down the river. He sets up an elaborate scene; killing a hog and smearing its blood around the cabin, stealing corn and whiskey, which makes everything look like the house had been robbed and Huck had been killed.
Huck floats down the river till he gets to a nearby island, called Jackson's Island, where he hides and keeps cover from the search party which is looking for his dead body. One day, when Huck was wondering around exploring his island, he happens upon a Negro friend named Jim. Jim and Huck Finn are good friends and Jim is on the run too, so they both team up and build a more substantial fort on the island. They catch fish for food and lead a fairly good life for a little while. They even robbed a house which was floating down stream; they got eight dollars and some supplies. However, eventually the people of St. Petersburg get a clue and go after Jim, who ran away from his owner. The two boys are forced off their island and drift down the river on a raft which was made out of odds and ends they got out of the river.
The two boys float down the river by night and hide when the day breaks. They continued catching fish and lived a pretty decent life, until one day. It was a fairly heavy storm and the boys were caught in the middle of it. As they floated around, they spotted a fairy boat which had run aground. They boarded the ship with plans to rob it, however plans changed when two men are discovered on the boat who want to kill this other man. The boys get off the boat as fast as possible and continue down stream to a city that's far enough from St. Petersburg so...
