Well the new "The Hitcher Hikers Guide To The Galaxy" book is being written by Eion Clofer... (see Artemis Fowl)
I never read a hitcherhikers guide book before. But if we are to judge him from his last book (Artemis Fowl vol 6. The Time Paradox) then its going to be pretty awful. Hopefully it's just the Artemis Fowl series that are getting progressively worse and not his talent.
Again this is the guy who admitted he wrote "Die Hard, with fairy's"
