When Natasha "Tasha" Joon accepts an invitation to read from her gender memoir to a feminist bookstore, she thinks it's one of her many stops on her publicity tour organized by her best friend and secret-crush Lydia. As it turns out, the audience that awaits her is far more sinister than she ever thought possible, and Tasha is soon cursed.

Instead of falling into despair, she and Lydia fall in love. Later on, Tasha realizes she has a tumour in her stomach that is rapidly growing. Then appears to move, as if it is a life force all its own. She and Lydia, both trans women, come to the same strange conclusion: Tasha is pregnant and this close to the holidays, it seems that she will be giving birth to the new messiah -- or a monster.

Now, with a possible monster baby on the way, Tasha and Lydia have more things to consider than they thought possible. When the coven shows up again, their supernatural adventure becomes that much more dangerous. Good thing Tanner Chapman, talk show host extra ordinate, can help sort out the matter of paternity once and for all.

Will Tasha's baby be human or demon, devil or angel? And is Lydia the father -- or mother? And who will get custody of the new miracle child: the two trans women who created life in spite of all odds, or the evil coven who only wish to destroy all light during the darkest time of the year?
