hen you enter the small shop you've been referred to, you're overwhelmed by the sheer number of books in the small space. Shelf after shelf, book by book, they line the walls. Towers of books stack up on the floor, some so tall and precarious, you wonder how they don't tumble. Carefully, you navigate your way through the labyrinth of knowledge surrounding you, until you find the owner of the shop in the back corner of the room. Sitting on an old leather chair in front of a brightly lit fireplace, he looks at you questioningly. He nods approvingly when you tell him what you're looking for and silently points to a row of nine large books bound in leather. Which one will you open first?
