This is a fairy tale about a magical world, magic, music, and a brave girl who, together with her friends and a magical cat, embarks on a distant journey to save her friend and an entire world.
Linni breaks an ancient taboo: in her village, named after a mysterious lurka — a magical instrument resembling a violin — girls are not allowed to touch it until they are 12 years old. But when music takes the soul of her best friend to the mysterious Dals, the girl realizes — only she can set everything right.
Together with Elias, who is in love with Saira, Linni sets off to the Broken City, where science and magic are in eternal conflict. There, she encounters: researchers with their dangerous machines, ready to turn Elias into a weapon, magicians who have recognized Linni as the Girl from the ancient prophecy — the one destined to receive the Crown of Two Worlds, as well as a Half-Cat — a mysterious creature whose fate is intricately linked with her own.
But when a mad scientist kidnaps the medicine for Saira, Linni has to do the impossible — enter the Dals and risk her own life to save her best friend... and decide whether she is ready to accept the Crown of Two Worlds to forever reconcile two warring worlds.
