'A must-read for people who love stories as moving as they are horrific.' ―Booklist, Starred Review

Bram Stoker Award–nominee and USA Today bestseller Johanna van Veen unveils a sapphic folk-horror tour de force―perfect for fans of The VVitch and The Salt Grows Heavy. A skull's grin is eternal . . .

The year is 1635.

Sister Ursula, a young nun fleeing the ruins of her convent, and Elsebeth, a sharp-witted peasant, escape a band of marauding soldiers and disappear into the Bavarian forest. War scorches the land, and no one survives it alone. Amid the devastation, they find something in the arms of a dying man: the gilded skull of a saint.

It is said that if you reunite the saint's skull with her body, a wish will be granted. Desperate for salvation, and each with secret desires of their own, Ursula and Elsebeth follow a ragged map across the blighted countryside. But darkness follows them. A necromancer, drawn to the relic's power. The saint herself, whispering at night. And as the lines between blessing and curse blur, the women must face a harrowing truth: the magic they seek comes at a cost.

At the journey's end, they'll face an impossible choice―one that could tear apart everything they know . . . or bind them to each other forever.
