It is 1502 and Rodrigo Borgia, a self-confessed womanizer and master of political corruption, is now on the papal throne as Alexander VI. His daughter Lucrezia, aged twenty-two, already three times married and a pawn in her father's plans, is discovering her own power. And then there is his son Cesare Borgia: brilliant, ruthless, and increasingly unstable. It is his relationship with Machiavelli that gives the Florentine diplomat a master class in the dark arts of power and politics. What Machiavelli learns will go on to inform his great work of modern politics, The Prince. But while the pope rails against old age and his son's increasingly erratic behavior, it is Lucrezia who must navigate the treacherous court of Urbino, her new home, and another challenging marriage to create her own place in history.
