No one knows Moonie Witcher, the Moon Sorceress who wrote 'The Girl of the Sixth Moon.' No one knows where she lives. It is only known that she has twelve cats and two owls who help her perform miracles, prepare magical potions, and write amazing stories. The Moon Sorceress believes that every child can become an alchemist-wizard, all they need to know is the secret alphabet in which the spells in the Book of Magic are written, a rich imagination, patience, and a love of animals. The main character of the Moon Sorceress's books, Nina, lives in Madrid. Her Russian name was given to her by her grandfather, the Great Magician and alchemist, who married the Spanish princess Maria Luisa España de Rigueira and lives in Venice. Nina has a star-shaped birthmark on her palm—the sign of a great alchemist. It is this mark that signals impending danger. Nina's grandfather dies under mysterious circumstances. And her life changes dramatically. With the help of a secret alchemist's alphabet, she must decipher her grandfather's writings and save the Sixth Moon from the treacherous Prince of Evil, Karkon. To do this, Nina will have to transform into a gnome, craft an elixir from dragon teeth, uncover the mystery of the winged lion from St. Mark's Square in Venice, travel to another planet, visit Easter Island, Ancient Egypt, and the pyramids of Mexico... Extraordinary adventures await them!
