Sister Marian the witch hunter is back for a new adventure in Marian Heretic: Book of Joan #1. The warrior nun returns to the apocalyptic world of monsters, witches, and strange convents for a one-shot by Tini Howard and Joe Jaro.

“With Sister Marian sidelined by a magical affliction, Ravenna must lead Sister Joan back into the City of Vespers to confront a new order of nuns wielding their own brand of witchcraft to keep Marian and her fellow Sisters out of the City,” per the description.

“Disguised as new members of the convent, Ravenna and Joan must uncover the nature of the witches’ magic – and the harm it’s inflicting upon their Holy Mother before things get too far out of hand,” the synopsis continues.

Howard and Jaro introduced Marian Heretic in a five-issue series that was released in 2025. She is guided by a goddess that is not recognized by the church, resulting in the Holy Father Church branding her order as blasphemers. In response, Marian struck a dark bargain to protect her order and fight the forces of darkness.

Marian Heretic: Book of Joan #1 features a main and variant cover by Jaro. The BOOM! Studios one-shot will be in comic shops on February 17, 2027.
