Books are just dead words on paper and it is the readers who bring the stories alive. Previously, writers wrote a book and sent it out into the world. A couple of months after publication letters from readers might arrive. And, leaving aside the professional reviews, it is really the reader's opinions that the writer needs. They vote for a book - and a writer - with their hard earned cash every time they go into a bookstore (or online - that's my age showing!) and buy a book.
