Finishing off the Huck Finn sequel, Tom and Huck Among the Indians, is I'm sure an interesting and enjoyable exercise and certainly an almost irresistible challenge for a true Twainiac. I find more interesting, however, conceptualizing (and writing at least part of)an original sequel. I'm surprised that more haven't tried it. The only one I have come across is Greg Matthews' Further Adventures of Huckleberry Finn.
