In the worlds of Chrestomanci, anything can happen. This adventure takes place in the Italian Dukedom of Caprona, where spells are as slippery and as tricksy as spaghetti Casa Montana and Casa Petrocchi look after the magical business in the Dukedom of Caprona, watched over by its magnificent guardian statue, the Angel. The families have been feuding for years, so when all the spells start going wrong, each naturally blames the other. Then young Tonino Montana and Angelica Petrocchi disappear. Could the terrible rumours of a White Devil who threatens Caprona be true after all?
