This thread is funny!
In Search of Lost Time is about three times the size of The Lord of the Rings, and though the writer, Marcel Proust, died before he did everything he wanted to do with it, one of the longest and most significant and complicated novels in the history of Western literature is very much complete, and its author ridiculously INFP. He (kind of) wrote down his entire life, systematically analyzing every aspect of it, before picking up the inevitable enormous amount of loose threads and tying them together by finally giving you the meaning of life in the end. The only reason something as cynic as postmodernism could ever happen after is because it's easier to have an opinion about a photograph of a nuclear mushroom cloud than it is to just finish a several thousand pages long novel.
Now ask me if I'm really sure Marcel Proust is an INFP after all, those ... words.
Stephen King is probably an INTP, but working on my degree in literature, I've in fact come to believe most writers are INFP. We have our Introverted Feeling trying to piece together the world emotionally, morally; and even those of us who are not writers go around expressing the results of this drive through their Extroverted Intuition; by way of what's not, but could be. Which is basically how you get into the Western canon. I'm looking at you Shakespeare, Keats, Baudelaire, Joyce (controversial!!), Emily Brontė, Dickinson, Camus, Salinger, Virginia Woolf, that Proust fellow, so on and so on.
Among the more contemporary, there's Haruki Murakami, Paul Auster, David Foster Wallace, Miranda July, Kazou Ishiguro, Jonathan Safran Foer, oh, and more.
