Ferius Parfax has a simple plan: kill every last inhabitant of the spell-gifted nation that destroyed her people. Killing mages is a difficult business, of course, so Ferius undertakes to study the ways of the Argosi: the loosely-knit tribe of tricksters known for getting the better of even the most powerful of spellcasters. But the Argosi have a price for their teachings, and by the time Ferius learns what it is, it may be too late. 12+ Perfect for fans of Terry Pratchett and Ben Aaronovitch.
