The Exilium is an institution for unworthy students - a place where no one goes by choice. However, now Sophie and her friends are outcasts, and it is in the Exile that the answers to the questions that affect not only the girl's life but also the very existence of the Lost Cities are hidden. By joining the Black Swan, the friends uncover many secrets - more terrible than they could have imagined. Meanwhile, the Unseen are plotting more and more insidiously, and a disease is spreading through the forests that threatens the entire dwarven race. Sophie and her friends take up the fight against evil, realising that choices are never easy and that blind trust will have irreparable consequences... This time, Sophie must risk everything to uncover the truth that will either save her world or destroy it.
