Without further details, we can't tell who the author of the 'new book story' might be. It could be a self - published author trying to make a name for themselves with an original and unique story. Or it could be an established author who is known for a particular genre, but has now ventured into a different type of story for this 'new book story'.
Since we only have the term 'new book story', it's impossible to know the author. There could be a new and upcoming author who wrote it, or it could be from a well - known author who has just released a new work. We would need more details like the genre, publisher, or some plot points to even start guessing the author.
