Seraphine Voss has exactly one magical gift: a small, cold light in her palms. It is not impressive. It is also nothing. When her sister is taken to settle a Fae debt their dead father made, Seraphine walks into the Court of the Seelie Star with nothing but her steadiness, her mother's knife, and the terrifying certainty that she is not leaving without Mira. What she bargains for is one year of service. What she finds is an archive full of buried secrets, three Trials designed to break her, and a lord who holds the weight of the world in the dark every night and calls it duty. She came to pay a debt. She stayed because she chose to. A slow-burning Fae court romance for readers who want their heroine to win with her mind.
