Patrick Paniter was James IV's right-hand man, a diplomatic genius who was in charge of the guns at the disastrous battle of Flodden in September 1513 in which the English annihilated the Scots. After the death of his king he is tormented by guilt as he relives the events that led to war. When Louise Brenier, daughter of a rogue sea trader, asks his help in finding out if her brother Benoit was killed in action, it is the least he can do to salve his conscience. Not satisfied with the news he brings, Louise sets off to find out the truth herself, and swiftly falls foul of one of the lawless clans that rule the ungovernable borderlands.
