You walk into a store where shelves are stacked to the ceiling with books as large as paving stones bound in leather; books the size postage stamps in covers of silk; books full of peculair symbols and a few books with nothing in them at all. You decide to stop at a book called, Curses and Countercurses ( Bewitch Your Friends and Befuddle Your Enemies with the Latest Revenges: Hair Loss, Jelly-Legs, Tongue-Tying and Much, Much More ) by Professor Vindictus Viridian, while you wait for some help.
