When seventeen-year-old Nor rescues a captured faerie in the woods, he gifts her with a magical golden thread she can use to summon him for a favor. Instead, Nor uses it for a con—to convince villagers to buy straw that can be transformed into gold. Her trick works a little too well, attracting the suspicion of Prince Casper, who hates nobody more than a liar. Intent on punishing Nor, he demands that she spin a room of straw into gold and as her reward, he will marry her. Should she refuse or fail, the consequences will be dire.
