WHO'S GOING TO WRITE the next Harry Potter? It may be you. And I don't mean the next popular book sensation. I mean the ACTUAL next Harry Potter, after Deathly Hallows. That's what I surmise from the gossip I heard today from contacts at the London Book Fair. Borders has agreed to distribute two Harry Potter books which are unauthorized and have no connection to JK Rowling. One is called The Great Snape Debate and the other is The Unauthorized Harry Potter. Look out for legal fireworks! It's an exclusive deal to Borders only until September, after which other bookshops can get them.
