Now a major film, this is a dramatic reinterpretation of the life of Mary Queen of Scots by one of the leading historians of this period. For centuries, Mary, Queen of Scots has been a figure of scholarly debate. Where many have portrayed her as the weak woman to Elizabeth's rational leader, John Guy reassesses the young queen, finding her far more politically shrewd than previously believed. Crowned Queen of Scotland at nine months old, Queen of France by age sixteen and widowed the following year, Guy paints Mary as a commanding and savvy queen who navigated the European power struggles of the time to her advantage. Her life was one of drama and conflict - Scottish lords constructed labyrinthine plots to wrest power from her and attempts to prove her claim to the English throne were thwarted by English ministers bent on protecting Elizabeth. My Heart is My Own re-examines the original sources, resulting in a riveting new argument surrounding Mary's involvement in her husband Lord Darnely's murder and her subsequent marriage to his suspected assassin. Guy's accessible treatment of the well-trodden story, his deft storytelling and insightful new arguments provide compelling and dramatic reading. 'An absorbing biography . . . meticulously researched . . . scholarly and intriguing' Peter Ackroyd, The Times 'Rarely have first-class scholarship and first-class storytelling been so effectively combined' John Adamson, Daily Telegraph John Guy is an award-winning historian, accomplished broadcaster and a Fellow of Clare College, Cambridge. His previous books include the highly acclaimed dual biography A Daughter's Love: Thomas and Margaret More a history, Tudor England, which has sold over 250,000 copies worldwide and a biography of Thomas Becket, published in 2012.

Mary Stuart, Queen of Scots, was one of history's romantically tragic figures. Devious, naive, often highly principled, beautiful, and sexually voracious, this was a woman who secured the Scottish throne and bolstered the position of the Catholic Church in Scotland. Her endless plotting, including a likely involvement in the murder of her husband Lord Darnley, eventually led to her flight from Scotland and imprisonment by her equally ambitions cousin and fellow queen, Elizabeth of England. And yet when Elizabeth ordered her unpredictable rival and kinswoman to be beheaded in 1587 she did so in resigned frustration rather than as act of political wrath.Was the beheading of a cousin truly necessary? Did Mary, though churlish, petulant, and often disloyal, really deserve to forfeit the compassion of her cousin, a woman who from childhood had been her friend and playmate? Mary's fate was to be born to supreme power, but she was totally lacking in the political ability to deal with its responsibilities. This was the tragedy that turned her life into a study in failure. The extraordinary story of Mary, which has inspired the great poets, playwrights, and operatic composers of the 19th and 20th centuries, is one of the most colorful and emotionally searing tales of western history, and is here told by a leading specialist of the 16th century.
