Elena Frost has spent her life being called worthless. Born without a wolf in a world where a wolf is everything, she is the spare daughter of the Pale Tide clan—kept alive for one purpose only.
When her sister Clara refuses the marriage alliance, Elena is dressed in a wedding gown stitched with black runes and sent across the sea as the substitute bride. Her groom is Rowan, the Fire Wolf King of Ashen Moon: a man who burned three clans to ash, whose eyes burn gold-red, whose beast is said to devour anyone who touches him.
Elena would rather die. On her wedding day she throws herself from Broken Moon Cliff.
The chain that drags her back does not save her. It sells her.
But the “wolfless trash” they traded away carries something none of them understand. Sealed inside the jade wolf pendant at her throat is a silver-blue wolf that has waited ten years to open its eyes. In her veins runs first-generation Moonblood—the bloodline the Seven Clans buried, hunted, and erased from history.
The marriage contract is worse than a cage. Every clause hides another. Silence is consent. A vow made in ice can never be broken. The ancient covenant that binds Elena to Rowan was never a romance. The bride delivers Moonblood. The groom delivers royal fire. Two people harvested by a machine older than both their kingdoms.
What her enemies never calculated is what happens when the sacrifice stops running.
