Heir. The Secret of the Palace Book

During a tour of the Royal Palace, schoolboy Ethan finds an ancient book of fairy tales, all of whose margins are filled with mysterious notes. Dreaming of becoming a real detective, the boy decides to start an investigation. But he... does not suspect that his fate is intertwined with that of Xandi — the heir to the throne, who also wants to uncover the secrets of the ancient tome. The two boys are separated not only by status but also by time — a full hundred five years. How can they solve the case when there is a temporal chasm between them? What is encrypted in the book? Could it be spells against ghosts from the palace park, or the coordinates of a place where treasures are hidden? During the investigation, the boys will confront terrifying events, a series of inexplicable coincidences, intrigues, and betrayal. Will they be able to uncover all the secrets hidden in the old book? And the most important question — will love and loyalty prove stronger than hate and revenge?
