Harry Potter fans are signing petitions asking JK Rowling to continue writing stories about the boy wizard. Rowling is on record saying: “I think that Harry’s story comes to quite a clear end in Book 7,” she said.” But I have always said that I wouldn’t say never. I can’t say I will never write another book about that world, just because I think: ‘What do I know, in 10 years’ time I might want to return to it’. But I think it is unlikely.”
