Nor was once the happy daughter of a miller, but that was before her father died in the Southern War and soldiers set fire to her village. Now, she's a 17-year-old swindler, performing whatever tricks and deceptions will bring in enough coin to feed her and her brothers. One day she finds a faerie boy being held captive by outlaws. Though Nor knows all the tales of the fay and their deadly blood magic, she goes against her better judgement and frees him. In return, the beautiful and mysterious faerie, Pel, gifts her with a golden thread.

Nor decides to use the thread to convince local villages that she can spin straw into gold, but just as the con begins, Prince Casper arrives in town. Seeing through her deception, Casper intends to make an example of Nor, forcing her to spin all her straw into gold, with the promise of marrying her should she succeed. But should she fail, her life and those of her brothers will be forfeit. In desperation, Nor calls on Pel for help, even knowing that his dark magic comes with a price.

From thief to future queen, Nor's story has only just begun. Attacks from the fay force Nor to question her friendship with Pel, while preparing for her life as a queen makes Nor wonder if this is the life she truly wants to lead.
