There won't be any book, it's just talk. The same goes for a movie. At most, a few pages of text might be produced. Writing a book takes time, not just an hour a day to type about some unknown topic. You need characters, a plot, and a general idea of what the heroes will be doing. I once found a book about the heroes online, but it was some kind of mirror site, and I couldn't download it. But there are books available, and it's better to read them than to try to come up with something yourself.
