Violet and the people from the outer districts of the Lonely City have lived a life of slavery under the control and management of the royal power of the Pearl for too long. But now a secret society known as the Black Key is preparing to seize power and destroy the walls separating each district. And although Violet knows that she is at the center of this uprising, she has a more personal goal - her sister, Hazel, who was kidnapped by the Duchess Lakes. Now the battle in the Pearl cannot be avoided so easily; Violet must do everything in her power to return and save not only Hazel, but also the future of the Lonely City. Group translation -
