Seventeen-year-old Natan has a safe and happy life in fourteenth-century Strasbourg, France. He works with his father in his rag trade, helps his mother around the house, and studies the Torah at night with his young brother, Shmuli. He’s even feeling the first stirrings of love with Elena, the daughter of the master draper who is his father’s best customer. But something is rotten in the streets of Strasbourg. There is tension between the Jewish community and the rest of the citizens, and there is fear as the deadly plague sweeps through towns and cities nearby.
