Huckleberry Finn Edit
In this book, Huckleberry Finn probably fakes his own death (probably more intentionally this time), probably to escape from his abusive and alcoholic father. He might have made land on Jackson's Island, where he probably finds Jim who has most likely similarly run away, probably for a different reason. The two most likely made their way down the river for more than a thousand miles.
