She has been poisoning the man who murdered her family for three years. The problem is he still will not die. Sylvan Ashborn is the last surviving princess of a kingdom reduced to ash. Hidden inside the palace of the Lycan King who ordered her people's slaughter, she works in his kitchens, grinds nightshade into his wine, and counts down the days until his body finally gives out. She has no fear left. No future planned beyond his death. No identity except the hate she has carried since she was twelve years old and watched her mother choose to die so she could live. Then King Theron Blackwater walks into the kitchens, looks directly at her — invisible, forgettable, nobody — and tells her to serve him personally. And nothing about him matches the monster she has spent twelve years rehearsing her revenge against. He is haunted by something she cannot name. Cursed in ways she is only beginning to understand. And when the mate bond ignites between them, it threatens to unravel every certainty she has left. Including the poison she cannot stop adding to his wine. She came to his palace to end him. She never planned to be the only one who could save him.
