Tik-Tok of Oz begins when Ann Soforth, queen of Oogaboo decides to conquer Oz. When she sets out with her army towards the Emerald City, Glinda finds out immeadiately about it in her book of records. She then changes the army's road direction, over the deadly desert over to the Nome King's Dominions.

Meanwhile, a girl named Betsy Bobbin and her mule Hank are shipwrecked on the shores of the Rose Kingdom after their ship sinks. They go to a nearby greenhouse, where a bunch of female roses cast them out.

Then who should come crashing through the roof than the Shaggy Man. He and Betsy pick a rose princess, and proclaim her the new ruler of the Rose Kingdom. However, the roses don't wan't the rose girl, whose name is Ozga, as their ruler, so he to is cast out of the Rose Kingdom. They then travel over a bridge to the Nome Kings Dominions, where they find Tik-Tok crashed in a well.

You will have to read for yourself what happens after that. This is quite possibly the most comical of all the Oz books.
