My husband has been listening to the audiobooks of the Dresden series of books. Whenever we travel together, he'll put on a book for me to "read." They are quite funny. One of the books we recently listened to had a war between the different factions of fairies. Fairies, in this world, are weak against steel. Dresden equipped some pixies with utility knives. Since the pixies were holding the plastic casing, they didn't get harmed by the metal. When they cut one of the fairies with the blade though..... The books are read by James Marsters, also known as Spike on Buffy the Vampire Slayer. He is really good. If you get a chance to listen to the books, do it. You won't regret it.
