Gemma Doyle, sixteen and proud, must leave the warmth of her childhood home in India for the rigid Spence Academy, a cold finishing school outside of London, followed by a stranger who bears puzzling warnings. Using her sharp tongue and agile mind, she navigates the stormy seas of friendship with high-born daughters and her roommate, a plain scholarship case. As Gemma discovers that her mother's death may have an otherworldly cause, and that she herself may have innate powers, Gemma is forced to face her own frightening, yet exciting destiny . . . if only she can believe in it.
