The Surprising Adventures of the Magical Monarch of Mo and His People (copyright registered June 17, 1896) is the first full-length children's fantasy book by L. Frank Baum. Originally published in 1899 as A New Wonderland, Being the First Account Ever Printed of the Beautiful Valley, and the Wonderful Adventures of Its Inhabitants, the book was reissued in 1903 with a new title in order to capitalize upon the alliterative title of Baum's successful The Wonderful Wizard of Oz. The book is only slightly altered—Mo is called Phunniland or Phunnyland, but aside from the last paragraph of the first chapter, they are essentially the same book. It is illustrated by Frank Ver Beck.
Mo is much more of a nonsense book than Oz, bringing to mind Lewis Carroll's Alice's Adventures in Wonderland, which is probably what the original title referred to.
Each chapter is a different story, unlike Baum's other books, which are full length stories. They do, however have a general throughline, and can be seen as an episodic novel.
Chapter One has no plot, but rather is a basic description of the Land of Mo, or "The Beautiful Valley". It explains that everyone in Mo is happy, and that the people never need to work, because everything they could desire grows on the trees, including items such as clothes. In A New Wonderland, the author mentions planning to move there himself, but this was omitted from subsequent editions.
Chapter Two: The Monarch of Mo goes to fight the Purple Dragon, which has just eaten all of the caramels in the land. The Dragon bites off his head, and the King is forced to go home headless. The King tries to make the best of it, but the Queen complains that she cannot kiss him anymore, so he issues an edict saying that whoever can make him a new head will get to marry one of the princesses. After two failures, a durable head is made out of wood by a wood-chopper. The Purple Dragon finds the wood-chopper and bites his head off, replacing it with the King's head. When the wood-chopper appears in court, he switches heads with the King, so that the King has his own head again and the wood-chopper has a wooden head he made. The King then tries to fulfill his promise, but the princesses refuse to marry a wooden-headed man. The wood-chopper then confronts the Purple Dragon, who tries its head-biting technique again, only to get its teeth stuck in the wooden head, thus letting the wood-chopper get his own head back so he can marry a princess.
