This year, best friends Sophie and Agatha are about to discover where all the lost children go: the fabled School for Good and Evil, where ordinary boys and girls are trained to be fairy-tale heroes and villains. As the most beautiful girl in Gavaldon, Sophie has dreamed of being kidnapped into an enchanted world her whole life. With her glass slippers and devotion to good deeds, Sophie knows she'll earn top marks at the School for Good and join the ranks of past students like Cinderella, Rapunzel, and Snow White. Meanwhile, Agatha, with her shapeless black frocks and wicked black cat, seems a natural fit for the villains in the School for Evil. The two girls soon find their fortunes reversed—Sophie's dumped in the School for Evil to take Uglification, Death Curses, and Henchmen Training, while Agatha finds herself in the School for Good, thrust among handsome princes and fair maidens for classes in Princess Etiquette and Animal Communication. But what if the mistake is actually the first clue to discovering who Sophie and Agatha really are?
