Night Watch is the 6th book in the Watch subseries of Discworld.
Surprisingly, I enjoyed this one pretty well. I say “surprisingly” because, as I’ve said in other reviews, Vimes often gets on my nerves. This book focuses on him very heavily, more than any other book since the first Watch book. However, we see more of the sarcastic and clever aspects of Vimes which I do enjoy and far less of the bitter, woe-is-me, self-destructive aspects which drive me crazy.
This is a time travel story. Vimes accidentally gets thrown back in time, to a point shortly after he had first joined the Watch. History of course gets changed, and now he has to make sure events happen that will keep his future in-tact.
It wasn’t a completely riveting story, but it had its fun parts. Some of those fun parts came from seeing various other Discworld characters at an earlier stage in their lives and learning what they were like before the series began. I particularly enjoyed meeting a younger Vetinari, a character I’ve enjoyed since he was first introduced.
