Strange events disturb the calm everyday life of the northern shore of Lake Balaton. The people of Soktornyú Castle in Tihany are preparing for a celebration: Princess Helka will soon officially become the heir to the throne. But our hero is bored with the commotion, he runs away to the forbidden forest to eat strawberries. Meanwhile, in the nearby Burok Valley, creatures with a dark soul gather to destroy the peace of Lake Balaton and take revenge on the princely couple, led by the cruel Bora. The legend of Helka is one of the forgotten myths of Lake Balaton. Péter Nyulász hid countless references and information in his hilariously humorous adventure novel bordering on fantasy.
