Today I find myself at Readercon.  Surrounded by ravenous readers of genre literature.  These are my people, or some of them at least.  I love story.  I just got off a panel called “The Unknowable Character” (I think).  John Crowley said, “I don’t mean to channel Rumsfeld, but when it comes to unknowable characters, there are known unknowns and unknown unknowns, and each is useful to a writer.”  (I’m paraphrasing from memory.)
