Isolde's life was never normal. She had never expected it to be.Born with silver hair, rare silver eyes, and abilities that unsettled everyone who got too close, she had spent her entire life being treated like something that did not quite belong. Her father looked at her and saw a stranger wearing his name. Her stepmother and stepsister, Delilah, despised her for reasons Isolde had long stopped trying to understand.She had learned to want little. To expect less.So when her father arranged her betrothal to a prince, she allowed herself, just once, to hope for a future. A life that was finally hers.It didn't last.It shattered the night she discovered that her betrothed had gone to Delilah's bed. Delilah, who had been selected for a secret mission — chosen to be a mistress for one of the most feared creatures alive — was no longer a virgin.The one rule that could not be broken had been broken, and her stepmother, never one to let an opportunity rot, found a solution before the dust had even settled.Isolde would go in her place.She would carry Delilah's name, offer herself to a creature whose very existence made kingdoms tremble.She goes to spy.She does not expect him to ask for her hand in marriage.She does not expect the way he looks at her — like she is not a stranger to him at all. And she cannot explain the strange, unsettling feeling that mirrors it back. The sense that she has known him too.But there is something in her that despises him.What she does not know — what she cannot yet see — is that she is something powerful. Something that came back for one thing alone.REVENGE.
