Katharina Schütz is a young woman growing up in sixteenth-century Strasbourg. Immersed in the mystique and works-righteousness of medieval Catholicism, Katharina's life is one of curiosity, mischief, sorrow, fear of purgatory, indulgences and all the struggles of a regular teen in a busy home, full of siblings and daily challenges.
