This book brings to life the story of Margaret Douglas, a shadowy and mysterious character in Tudor history - but who now takes centre stage in this tale of the bitter struggle for power during the reign of Henry VIII. Margaret is Henry's beloved niece, but defies the King by indulging in two scandalous affairs. Yet when the King turns against his second wife Anne Boleyn and declares his daughters Mary and Elizabeth bastards, it is Margaret he appoints as his heir to the throne. Imprisoned in the Tower on two occasions, it is the arrangement of the marriage of Margaret's son, Lord Darnely, to his cousin, Mary, Queen of Scots, that unites their claims to the throne and angers her uncle King Henry yet again. Yet this match brings tragedy, as her son is brutally murdered. As Margaret reaches old age, her place in the dynasty is still not safe, and she dies in mysterious circumstances. But was Margaret poisoned on the orders of Queen Elizabeth? This forgotten part of Tudor history is told here for the first time with all the passion and thrill of a novel, but this is no fiction - the untold story of this forgotten Tudor runs through the course of history, and she secured the throne for her Stuart ancestors for years to come.
