Prelude delineates the gay female experience through a poetic reconstruction of the girlhood of Catherine of Siena, a Catholic saint who lived in 1300s Italy and disobeyed her parents by refusing marriage to devote her life to God. Through a historical lens, Brynne Rebele-Henry examines the erasure of gay women's lives and offers a perspective of medieval queer girlhood while considering themes such as violence, desire, and the lesbian body.
