Anne Halford is a candy crafter with a single goal: earn the title of Silver Sugar Master, an honor granted only by the kingdom's royalty. To reach the royal capital, she purchases Challe, a powerful fairy warrior with a sharp tongue and a deep contempt for humans, as her bodyguard. Anne wants Challe as a companion rather than property, and she promises to return the fairy wing she holds over him once they arrive. Their journey through a kingdom where fairies are bought and sold forces both of them to confront the cost of trust across an unbridgeable divide.
