I like Eoin very much, and wish him well with the book. He'll probably write a sixth Hitchhiker's book with more enthusiasm, and certainly faster, than Douglas would have done. But it won't be a Douglas Adams Hitchhiker's book.
For the record, if I don't get around to writing a sequel to something while I'm alive, I'd very much rather that nobody else does it once I'm dead. It should exist in your head or in Lucien's library, or in fanfic. But that's me, and not every author feels the same way.
Выражаю неистовую солидарность с последним абзацем.
Невермор!
