The year is 799, and King Charlemagne awaits coronation as the Holy Roman emperor. But in the town of Würzburg, the young, willful Theresa dreams only of following in the footsteps of her scholarly father—a quiet man who taught her the forbidden pleasures of reading and writing. Though it was unthinkable for a medieval woman to pursue a career as a craftsperson, headstrong Theresa convinces the parchment-makers’ guild to test her. If she passes, it means access to her beloved manuscripts and nothing less than true independence. But as she treats the skins before an audience of jeering workmen, unimaginable tragedy strikes—tearing apart Theresa’s family and setting in motion a cascade of mysteries that Theresa must solve if she hopes to stay alive and save her family. A fugitive in the wilderness, Theresa is forced to rely on her bravery, her uncommon education, and the compassion of strangers. When she encounters Alcuin of York, a wise and influential monk with close ties to Charlemagne, she believes her luck might have finally changed. But the biggest secret lies between Charlemagne and her father. Theresa moves ever closer to the truth, bent on reuniting with her beloved father, only to discover that her family’s troubles are inextricably entwined with nothing less than the fate of an empire.
