The Ultimate Library

There is a variety of different books in this section, they all have different covers and different things on the covers, but no text. You pick up the first book on the shelf, it is black, with a bottle of pills on it. The second has a blue cover with a small rowboat. You look down the shelf, it seems never to end. You could start now, and lose yourself in a word of fantasy and books, or go to see if this shelf ever ends. Just remember, there will always be some sort of book that takes your fancy, somewhere in this endless bookshelf. You look behind you, hang on a minute, you can't see the library anymore. It doesn't matter though, maybe in one of these books, there is a way to get out. But maybe, just maybe, you won't want to.
