Award-winning journalist Caitlin Bergman's mother is dead - at least that's what she’s told everyone for the past 40 years. It’s easier to lie than to explain how Maya abandoned her only daughter before dropping off the map forever.

But when a rural sheriff invites Caitlin to the woods of coastal Oregon to identify her mother's remains, Caitlin drops everything to face the woman she's spent a lifetime hating. Unfortunately, the body - abandoned on the land of a reclusive cult, the Daughters of God - was left faceless. Instead, Caitlin finds the diary of a woman obsessed with the end of the world, one that hints the cult's spiritual leader knows the identity of Caitlin's real father. And she's not the only one looking for clues in her mother's writing. Johnny Larsen, a violent white supremacist whose family runs the county, thinks the Daughters of God kidnapped his teenage daughter - and he’ll do anything to get her back.

At the top of a hill, an army of women wait for the end of days. In the town below, the Larsens plot to purify their county. Caught in the middle, Caitlin must decide which is more important - learning the truth about her past or saving Mama Maya's chosen daughters from the end of the world.
