Who better to speak of Harry Potter? (Rowling on what happens after Deathly Hallows)
SPOILERS (major, massive spoilers) for Harry Potter and the Deathly Hallows, as J.K. Rowling does an online chat telling us more of what happened after that book and some of the background stuff that didn't make it into the books.
Not only are there spoilers, but there are details that (if you are like me) might make you wibble.
