And Alanna from Trebond happened to be born a girl! It's hard to live when you dream of becoming a knight, but instead you learn magic, singing and dancing. Alanna's twin brother Tom, on the contrary, wants to comprehend the science of magic and become a powerful sorcerer. One day, the guys decide to switch places: Tom goes to a monastery, where he will learn magic, and Alanna, pretending to be a boy, goes to the royal palace to enter the service of a page. But becoming a knight is not so easy. Before gaining the right to participate in battles, Alanna must learn not only to wield a sword properly, but also to distinguish enemies from friends. Only after going through the thorny path of victories and defeats, adventures and intrigues, faced with good and evil, will Alanna be able to fulfill her dreams and become famous.
