A masterful debut novel following a spirited young woman's explorations of faith, agency, and love in thirteenth-century Bruges.

Aleys is sixteen years old and unusual: stubborn, bright, and prone to religious visions. She and her only friend, Finn, a young scholar, have been learning Latin together in secret-but just as she thinks their connection might become something more, everything unravels. When her father promises her in marriage to a merchant she doesn't love, she runs away from home, finding shelter among the beguines, a fiercely independent community of religious women who refuse to answer to the Church.

Among these hardworking and strong-willed women, Aleys glimpses for the first time the joys of belonging: a life of song, meaning, and friendship in the markets and along the canals of Bruges. But forces both mystical and political are at work. Illegal translations of scripture, the women's independence, and a sudden rash of miracles all draw the attention of an ambitious bishop-and bring Aleys and those around her into ever-increasing danger, a danger that will push Aleys to a new understanding of love and sacrifice.

Grounded in the little-told stories of medieval women-mystics, saints, anchoresses, and beguines-and introducing a major new talent, Canticle is a luminous work of historical fiction, vividly evoking a world on the verge of transformation.
