Eoin Colfer is writing a sequel to the Hitchhiker's Guide series.
Whee! Eoin Colfer is fun, and fun is good! If you haven't read his books, well, you should!
--I'm not one of those people who think Hitchhiker's should NOT be tinkered with. And, considering the various transformations the original idea went through before it turned into a book, let alone a TV series or a movie, I don't think Douglas Adams did, either. I can't imagine an author less likely to shout, "You can't change it--my work is sacred!"
