In the fifth book of the decalogy, “The Emerald City,” dramatic events unfold in the Pink Country, where Ellie and Korina arrived to discuss with Stella a plan to fight against the Lord of the Underworld. One of the good sorceress’s maids of honor, the envious and power-hungry Agnet, decided to take possession of the Pink Country by deception country. Taking advantage of the opportunity, she stole the Golden Cap, with which she summoned the leader of the Flying Monkeys. The Flying Monkeys must take the sorceresses to the ominous city of Shadows, in which reigns the ghost king, the faithful servant of the Lord of the Underworld.
