Ellie Sinder is a Charmer—the most powerful of her age that St. Juno’s Academy has ever seen. But Ellie’s stepmother, Laurissa, wields manipulation and abuse to force Ellie to work her spells ever more intensely, for Laurissa’s profit.

Then a train from over the Wastelands arrives in New Haven, bearing on it golden boy Avery Fletcher, newly returned from prep school, wearing a sweater Ellie’d love to bury her face in and a smile as bright as his blond hair. Avery’s arrival sets Laurissa off on a dark and dangerous scheme—and this time the soul up for grabs is Ellie’s.
