Her grandfather bequeaths her not only a magical Book and other attributes of magic and alchemy, but also the main affair of his life—saving the planet Xorax, or the Sixth Moon. Nina and her friends take up the fight against dark forces: the Black Magician, Prince Karkon, and his henchmen. To break the evil spells and save Xorax—the planet of goodness and light—they must reveal four Secrets. In search of answers, the kids go to Easter Island, are transported to Ancient Egypt, and visit Xorax… In short, they will face extraordinary adventures and transformations.
