The Other Tudor Princess 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 she defies the king by indulging in two scandalous affairs and is imprisoned in the Tower of London on three occasions 'not for matters of treason, but for love'. Yet, when Henry 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. The arrangement of the marriage of Margaret's son, Lord Darnley, to his cousin, Mary, Queen of Scots unites their claim to the throne and infuriates Queen Elizabeth. Yet this match brings tragedy, as Margaret's son is brutally murdered. As Margaret reaches old age, her place in the dynasty is still not safe, and she dies in mysterious circumstances - was Margaret poisoned on the orders of Queen Elizabeth? Mary McGrigor tells this compelling and exciting part of Tudor history for the first time with all the passion and thrill of a novel, but this is no fiction - the untold story runs through the course of history, and Margaret secured the throne for her Stuart ancestors for years to come.

Isabella de Valois was 3 years old when, on a hot August day in 1392, her father suddenly went mad. Less than four years later, she was married by proxy to the English King Richard II and arrived in England with a French retinue and her doll's house. Richard's humiliating deposition and brutal murder by his cousin, the future Henry IV, forced Isabella's desperate return to France where she found her country fatally divided. Isabella's sister, Catherine de Valois, became the beautiful young bride of Henry V and is unique in history for being the daughter of a king, the wife of a king, the mother of a king and the grandmother of a king. Like her sister, Catherine was viewed as a bargaining chip in times of political turmoil, yet her passionate love affair with the young Owain Tudor established the entire Tudor dynasty and set in motion one of the most fascinating periods of British history. The Sister Queens is a gripping tale of love, exile and conflict in a time when even royal women had to fight for survival.
