Twelve year-old Montego al'Bou is an orphan, a provincial peasant boy left alone by the recent death of his grandmother. Possessing nothing more than his grandmother's cudgel, he strikes out to the capital where the influential Grappo have offered to bring him up in the luxury of an Ossan guild-family. He finds his welcome frosty, his new home full of confusing responsibilities. He quickly discovers that the greatest sin in the capital is to be born without money, and the classist elite will not hesitate to remind him of his humble origins. Montego dreams of being his own man, of making it in the cudgeling arenas of the Empire's deadly spectator sport where even a provincial can be worshipped like a god. But skill isn't the only barrier for a wannabe cudgelist. Without allies, cunning, and a helping of daring, he can't hope to make it in the capital.

Chaos is the word of the day in the provinces of the Ossan Empire. The city of Holikan has risen up in revolt, only to be put down again by the Ossan Foreign Legion under the command of Demir Grappo. But that wasn’t the plan, and Demir has fled his responsibilities after witnessing the brutality of his own troops. He wanders aimlessly, a husk of his former self, until his quest to escape his guilt crosses paths with a foreigner on a mission of her own. Far to the north, a holy sword has been stolen from the Court of Lilies. Squire Ciata tracks the thieves to an Ossan guild-family. She does not know the rules of this strange land, only that the sword does not belong to them. An army of enforcers stands between her and its return. A hopeless cause, if not for the help of a broken young man she meets along the way.
