Bargained to the Frost King

Marisol Vey has no name. She traded it for her brother's fever and the Frost King took the deal — took her with it. Now she works the ice halls of a court where heat is currency and every thrall has a number instead of a self. Kol the Unmelting has never lost a bargain. Marisol intends to be the first. But when she finds her mother's name in his ledgers — entered twenty-some years ago, next to a bargain no one remembers making — she realizes she isn't just his thrall. She's part of a debt older than either of them, and the only way to break it is to trust the man who bought her. The court is frozen mid-war, the thaw is coming anyway, and Marisol has to choose what's left of her to trade for it.
