Twirling Book Princess

The UU Library is theoretically the largest in the universe or, indeed, any conceivable universe; it has a diameter of about one hundred yards but, as far as we can determine, an infinite radius. The presence of so much stored magic does to time and space what a hot iron does to a pound of butter, so that you may well encounter places where the floor is now the wall, the books have turned into small clay models of hedgehogs and you yourself appear to be a device for coring apples. Students will therefore find it convenient to stick to the routes marked with chalk and the occasional banana skin.
