No, this is nothing official. This is something I've been working on for awhile. I was disappointed that there was no novelization of my favorite movie in the JP franchise. Therefore, I decided to write my own. As it happens, for any of the dialogue I haven't memorized, I've been using the transcript of the movie here on the Wiki in order to be as faithful to the film as possible. Here's a sneak preview. Ignore the highlights, they're from a friend, who's basically acting as editor for now.
So, what do you guys think? Is my writing any good? Is this a project you'd be interested in? Feel free to sound off!
