Three months after The Oath Breaker, oathblooms — eruptions of wild promise-magic — have begun in Veyne, the neighboring kingdom. The dispersed magic has found a new center: King Caelan, the boy Sera's dead sister trusted. With her gift burned out, Sera must stop Master Corvin, Veyne's oath-smith, from binding the grieving boy-king into a living ward-crown. The price of stopping him: every promise SHE speaks will bind HER, forever. Enemies-to-lovers romantasy — Book 3 of The Oath Thief series.
