It sounds so geeky, but I really do like studying and reading, and if I’m not working on Harry Potter, then my greatest relaxation is to sit with a book. That’s how I escape stress — in literature. I always have several books on the go at any one moment, so it’s no good you asking ‘What’s on the bedside table at the moment, Emma?’ because often I can’t even see the table! I think that all that reading is just about the only similarity I have with Hermione, if you ask me.
