5 stars Baum did it again with his fourth installment in the Oz series. Makes one ready to go and pick up the next tale. In this one, Dorothy and the humbug Wizard again re-unite after Dorothy and Zeb (her cousin) and Eurika (her cat) and Jim (the horse) are caught in an earthquake and therein the Land of the Mangaboos. More magic and logical nonsense ensues along with visits of past Oz friends, some new creatures and a reunion with Ozma in the Emerald City. There were some laugh-out-loud scenes as I read this to my boys. A great story all around.
