BOOM! Studios releases the one-shot MARIAN HERETIC: BOOK OF JOAN #1 on February 17, 2027, by Tini Howard and Joe Jaro, as Ravenna and Sister Joan go undercover to expose a rival order of witch-nuns.

The press release follows:

Media Release – Sister Marian is back, together with “her world of monsters, witches and bizarre convents stretched across an apocalyptic world” (AIPT)! Our favorite warrior nun has returned for a bold, new, irreverent one-shot, MARIAN HERETIC: BOOK OF JOAN #1, featuring dynamic duo Tini Howard and Joe Jaro’s signature storytelling of rebellion, sexuality, and the hard truth that sometimes in order to follow your faith, you have to sin a little.



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.

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

MARIAN HERETIC: BOOK OF JOAN #1 is available for pre-order from your local comic shop until January 4, 2027, and will hit shelves on February 17, 2027. Digital copies can be purchased from content providers, including iBooks, Google Play, and Kindle.
