In the lands of Bethel, where the Prophet's word is law, Immanuelle Moore's very existence is blasphemy. Immanuelle does her best to worship the Father, follow Holy Protocol, and lead a life of submission, devotion, and absolute conformity, like all the other women in the settlement. But a mishap lures her into the forbidden Darkwood surrounding Bethel, where the first prophet once chased and killed four powerful witches. Their spirits are still lurking there, and they bestow a gift on Immanuelle: the journal of her dead mother, who Immanuelle is shocked to learn once sought sanctuary in the wood. Immanuelle finds herself struggling to understand how her mother could have consorted with the witches. But when she begins to learn grim truths about the Church and its history, she realizes the true threat to Bethel is its own darkness.
