Flodden , September 1513. Across a boggy valley, two armies confront each other. The Scots, backed by European allies, have superior numbers and the latest cannon to challenge a depleted English force. The English are furious and humiliated that they are not fighting alongside King Henry against their real enemy in France. The Battle of Flodden would prove one of the bloodiest ever fought on British soil, shaping Scottish national identity to this day. Sir Thomas Howard, shrewd but ancient, leads the English forces. Alexander, 3rd Lord Hume, bold but impetuous, leads the Scots. Isabella Hoppringle, Abbess of Coldstream, young and determined, struggles to keep her footing among the tides of violence. John Heron, Bastard of Ford, swaggering, violent, and disreputable, the black sheep of a good English family, finds profit while men die. Blood Divide sets us right at the heart of the action; the stink, sweat and fear, the curtain of red mist.
