Severin is the heir to the Dragon Moors, but for now she is just a frightened child, whose mother, the strongest of the Margs, is sent to a battle that could end in defeat for their family. Annabelle is the future mistress of the High Castle, but for now she is only doing what who gets into trouble, fights with an earth rat, luring it out from under the bed and accidentally witnesses a conversation between her father and a man who will play an important role in her life. Elliana is the heiress of Isora, a kingdom that practically destroyed the Severin family. But now Elliana is just a baby who was taken away from her mother, and His Majesty’s magician did not save the girl, allowing his king to lock his own daughter in the White Towers, from where she cannot escape. Their lives are so different, but fate has its own plans. The girls will have to grow up and become stronger in order to one day put an end to all wars and hostilities, uniting the two worlds. The world of floating islands and the world of fallen islands.
