This sixth installment of Sukhinov's spectacular "Emerald City" saga introduces lovely but cold Langa, Princess of Darkness, henchwoman to the evil Pakir. At her command, the alchemist Parcelius does his utmost to produce the devastating Black Flame, which Pakir needs for his conquest of Magic Land -- and the world. When his efforts fail, he leads an army of golems to a certain underground cavern, where the Flame is reputed to be already, and the saga assumes a cosmic dimension.
