JK Rowling is getting paid $8M for her next novel and it is not about Harry Potter or anyone in Harry Potter. Ostensibly it is for adults, but I think adults made up about half her Harry Potter readers so I think it is unfair to say those books were for kids. Would you read a 7 year old Deathly Hallows? I don't think so. No one knows what the book will be about and I do wonder whether it will be any good, but at least she did not just give up on writing like so many authors who get one great book or series out of themselves and then just go into hiding because they can't write anymore.
