No one understands the complexity and plights of Catholicism like a teenage lesbian, especially one whose only friend happens to be a figment of the 13th-century saint Joan of Arc. The Book of Joan takes an absurdist look at the mind of Grace as she, and a production of her own imagination, unpacks her burgeoning sexuality, mental health, and the restrictive Catholic world she inhabits, all before she has to leave for school. This dramedy reflects upon the identities we foster under states of repression, and who knows repression better than a Catholic teenage lesbian?
