What I Did On My Holidays
This book was written by Twoflower after his return from Ankh-Morpork to the Agatean Empire. It is the narrative of the adventures that befell him during his holidays in Ankh-Morpork and other parts of the Discworld (actually the adventures from the books The Colour of Magic and The Light Fantastic).
Twoflower, the first tourist of the rather strict Agatean Empire, could not have imagined the effect his book would have on the population. With his usual naivety and innocence, he narrated his adventures in the most colourful details. The book would have become an instant bestseller, had it not been for the traditional rulers of the Empire, who wanted their people subdued and oppressed and not to have fresh ideas about going abroad. As a result, Twoflower got imprisoned as enemy of the state, and his book was banned as dangerous material.
And the book was dangerous in a way: In fact, underground organisations of rebels still made illegal copies of the text and thus promoted their revolutionary ideas. With the help of Rincewind, Cohen the Barbarian and his Silver Horde, they finally brought about the downfall of the old imperial ways in the book Interesting Times. The Agatean Empire had to open up their doors and give their people more freedom.
