With the novelistic vividness that made his National Book Critics Circle Award finalist Queen of Scots "a pure pleasure to read" (Washington Post BookWorld), John Guy brings to life Thomas More and his daughter Margaret— his confidante and collaborator who played a critical role in safeguarding his legacy. Sir Thomas More's life is well known: his opposition to Henry VIII's marriage to Anne Boleyn, his arrest for treason, his execution and martyrdom. Yet Margaret has been largely airbrushed out of the story in which she played so important a role. John Guy restores her to her rightful place in this captivating account of their relationship. Always her father's favorite child, Margaret was such an accomplished scholar by age eighteen that her work earned praise from Erasmus. She remained devoted to her father after her marriage—and paid the price in estrangement from her husband. When More was thrown into the Tower of London, Margaret collaborated with him on his most famous letters from prison, smuggled them out at great personal risk, even rescued his head after his execution. John Guy returns to original sources that have been ignored by generations of historians to create a dramatic new portrait of both Thomas More and the daughter whose devotion secured his place in history.
