Sor Juana Inés de la Cruz
A 17th-century Mexican nun, poet, scholar, and playwright who was a child prodigy and one of the most acclaimed writers of the Spanish Golden Age. She entered a convent at age 19 and later faced persecution from the Inquisition for her writings and ideas. Much of the novel focuses on her life.
Her writings challenged societal norms and ecclesiastical authority, leading to eventual censure. In Hunger’s Brides, her life serves as a focal point, examining themes of knowledge, autonomy, and resistance within a patriarchal society.
