I read a really good fanfiction story recently and wanted to have it made into a book on one of those book-printing sites, like lulu.com. I would only make one copy for my own personal use. I might also change the charactes and plot around a little, would this be legal? I was planning on not putting an author, obviously not crediting myself as the author. If changing it isn't legal, would just printing it out and not putting an author's name be legal?
