North America is a realm of kingdoms locked in battle over land, religion and honour. The northern Kingdom of Canada is plunged into turmoil when a Pretender comes to reclaim his birthright. The omens of civil war grip the kingdom, while in the south a conquering Empire looms closer. Five people are caught at the crux of this madness. A girl from Montreal with a rebellious streak finds herself in the company of revolutionaries. A grizzled veteran fights to bring justice to a ruthless and vengeful warchief-in-exile. The son of a baron, bright but naive, is tasked with the impossible by his king. In York, a rich but outcast student must decide his future in the face of an invasion, and on the Great Lakes, a widow with her own ship navigates both the waves and feudal politics. Beneath the gaze of the Wintermaker, these five must endure the coming strife and change Medieval America forever.
