Snowbound until spring in a crumbling castle of nightmares, Sienna is trapped with the dark, brooding Wolf who betrayed her and is clearly hiding something.
The longer she remains, the harder it is to resist the slow-burn pull between them, an enemies-to-lovers bond that could ruin them both.
By night a ghost draws her into forbidden dungeons and shadowed corners, where fae with dark appetites wait to claim her, and she cannot tell whether the wraith means to warn her or lead her to death.
The Dead Queen and her mysterious Wolf already haunt the halls, but a visitor washed onto the frozen shore brings a colder warning: the Fox King is coming.
Her father will stop at nothing to see her dead and secure the succession for his illegitimate son, yet if she masters her volatile power she could defend the cursed castle, kill him, and take his throne.
Copper-clad soldiers march north with that bloodthirsty king as whispers rise of broken bargains, ravenous monsters, and ancient fae kings and queens stirring after thousands of years.
