In the modern Kingdom of Ireland, few mortals believe in the fairy folk. Without that belief, the fairies are dying. Finvarra, the King of the Fairies, would rather dance than worry—but he must have a mortal dancing partner. When Janet Gleason’s grandfather becomes the new U.S. Ambassador to Ireland, the sixteen-year-old orphan must leave Boston and her friends behind. Janet is lonely in Dublin and unused to her grandparents’ stuffy social life. An invitation to a royal ball terrifies her. She can’t even waltz and dreads embarrassment. Finvarra’s fairy witch overhears her fervent wish to learn to dance. Seventeen-year-old Prince Liam Boru loathes the idea of escorting another spoiled American girl to a ball. In fact, he detests most of his royal duties. He dresses down to move through Dublin unnoticed and finds himself on his royal backside when Janet crashes into him. Intrigued, he asks to see her again, and she willingly agrees. Unaware of each other’s identities, they arrange to meet. When they do, the fairies steal Janet away. Liam's attempts to find her trigger a series of frustrating misadventures. Can he and Janet outwit a treacherous fairy king who's been hoodwinking mortals for centuries?
