Skip books kind of have an interesting basic premise – it's an enchanted book so potent that reading it not only convinces you that you've lived through the author's adventures, but convinces all the author's friends as well. But the results probably hew too close to canon for good original-character RP, unless perhaps you invent a similar book that convinces you of something else.
Perhaps this other book doesn't work quite so well, and one day this complete stranger walks in absolutely insistent that he's a well-known author or journalist despite clearly not being them.
