The keeper
(Book)

Ordinary books don't move. Ordinary books are quite happy waiting to be picked up. You could leave an ordinary book somewhere uncomfortable--at the bottom of a dark schoolbag or in the middle of a shop window--and it wouldn't dare budge, even if it had to sneeze. Nobody had told the Book of Magic this, though, so it jumped into Ois�in's hands without so much as a flap of its pages.
