In preparation for reading the last installment of the Harry Potter books, I had to update myself; I re-read the last two on the way back from San Francisco. It is a testament to how complicated the books actually are, that I had to do it at all. Every spell, every character, every place, every bit of magic is as deeply layered as Tolkien (I know, that's sacrilege). So, today we're talking to the continuity editor for the American version of the book; it's her job to make sure that every single spell, wand flick, and recipe for butterbeer are spelled and described accurately. If you think that you can stump her — I dare you. Expelliarmus!
