(Not exactly a serious novel)
A modern office drone works overtime, catches some sleep, and wakes up to discover he has become the prime minister of a kingdom...
What? The treasury records are hundreds of cartloads of parchment scrolls? Someone, draw me a T-account! What? The cabinet is at each other's throats over the military budget? One SWOT analysis, and the ministers are frozen on the spot!
With Chief Secretary Humphrey smiling as inscrutably as ever, every modern term could be a death sentence. Should he become a complete puppet and eke out a life of luxury? Or use twenty-first-century management science to take on this terrifyingly efficient feudal bureaucracy?
Years later, in the face of an unprecedented famine, the once all-powerful chief secretary bows deeply before a map of “grid-based management.” “Yes, Prime Minister!”
It's very interesting. Of course, I don't recommend reading it in one sitting. I suspect it has an AI direction, but it's not a big problem. Watching it three times a week is enough. Watching too much will make you feel bored. After all, politics always complicates problems.
