This was a typical Oz novel. The premise of the novel is that all the charactrs are planning birthday surprises for Ozma, and the novel recounts their adventures while obtaining the best surprises. It suffers from the same malady of several other Oz novels, in that the plot is not a cohesive whole so much as a collected sequence of events, some of which are not directly related to the others. Still, it was entertaining, a fun read.
