Lyman Frank Baum (1856-1919) was a world-renowned American writer. He created the magical land of Oz in his imagination and wrote many books about it. This time, readers, along with the ruler of fairyland, Princess Ozma, and her best friend Dorothy, will travel to the lands of the skeezers and flatheads to find out why the two peoples suddenly began to feud with each other. However, events will develop so rapidly and unpredictably that the peacemakers will not only not help the war, but will also find themselves trapped on a glass Island-the skeezer state, magically submerged to the bottom of the lake. After learning about this from The Book of events, The Good sorceress Glinda gathered volunteer assistants and immediately went to the rescue.
