1537. As the year to end all years rolls to a close, King Henry VIII vents his continuing fury at the pope. The Holy Roman Church reels beneath the reformation and as the vast English abbeys crumble the royal coffers begin to fill. The people of the north, torn between loyalty to God and allegiance to their anointed king, embark upon a pilgrimage to guide their errant monarch back to grace. But Henry is unyielding and sends an army north to quell the rebel uprising. In Yorkshire, Katheryn Lady Latimer and her step-children, Margaret and John, are held under siege at Snape Castle ... The events at Snape set Katheryn on a path that will lead from the deprivations of a castle under siege to the perils of the royal Tudor court. Intractable Heart is the story of Henry VIII's sixth and final wife.
