The discovery of a hidden box of letters by Henry VIII's final wife forces a retrospective examination of the volatile and often fatal marriages of the English monarch. Following the death of the King in 1547, Catherine Parr uncovers correspondence from her five predecessors, each detailing the precarious nature of their existence within the royal court. The narrative utilizes these recovered documents to frame the personal experiences of the six women who held the title of Queen. The text operates as a simplified historical narrative designed to provide insight into the domestic instability of the Tudor era.
