Katharina von Bora has seen nothing but the inside of cloister walls since she was five. In a daring escape, Katharina finds refuge with Martin Luther and seeks his help to pair her with the noble, wealthy husband she desires. As class tensions and religious conflicts escalate toward the brink of war, Martin Luther believes that each day could be his last and determines he will never take a wife. As the horrors of the bloody Peasant War break out around them, the proud Katharina and headstrong Martin Luther fight their own battle for true love, in one of the greatest love stories of history.
