The Magicians of Caprona is one of my favorite of the Chrestomanci books (Witch Week's pretty close up there too) It's just such a gorgeous book with a setting you NEVER see in most children's fantasy, or most fantasy in general. I keep secretly hoping one day someone will make a movie out of it. For the simple fact I want to actually hear the crazy screaming latin choruses of the big Petrocchi-Montana showdown.
