As a high school teacher myself, I wouldn't have any problem with it.? In
fact, I've written my own sequel to Huck, partly as a response to dares from
my students to put up or shut up (since I recommend this sort of thing as a
way to increase engagement with literature--parody, sequels, prequels, etc).
I wouldn't assign my own book, but our librarian asked for a copy of
it.?Mine may not be in Mr. Clinch's league, but if anyone wants to have a
look at it, you can get to it at
