“I wished I could visit a Museum of Unnatural History, but, even so, I was glad there wasn’t one. Werewolves were wonderful because they could be anything, I knew. If someone actually caught a werewolf, or a dragon, if they tamed a manticore or stabled a unicorn, put them in bottles, dissected them, then they could only be one thing, and they would no longer live in the shadowy places between the things I knew and the world of the impossible, which was, I was certain, the only place that mattered.
          “There was no such museum, not then. But I knew how to visit the creatures who would never be sighted in the zoos or the museum or the woods. They were waiting for me in books and in stories, after all, hiding inside the twenty-six characters and a handful of punctuation marks. These letters and words, when placed in the right order, would conjure all manner of exotic beasts and people from the shadows, would reveal the motives and minds of insects and of cats. They were spells, spelled with words to make worlds, waiting for me, in the pages of books.”  

—Neil Gaiman, from the Introduction to Unnatural Creatures (Harper Collins, 2013)
