Guards! Guards! is one of Terry Pratchett‘s Discworld novels and the first to deal with the City Watch.
[Yeah, I know I said I was gonna continue with Mort, but it seems to be the only Discworld book that deadra doesn’t own, so Death will have to wait… :)]

Plot:
A secret brotherhood, the Unique and Supreme Lodge of the Elucidated Brethren of the Ebon Night [not to be confused with other Brethrens] hatch out a plan to overthrow Lord Vetinari: They want to conjure up a dragon, let it be killed by a hero, who will then go on to be their puppet king.
Unluckily for them, Captain Sam Vimes of the Night Watch chooses exactly this moment to stop drinking and start using his brain.

Guards! Guards! was much more like I imagined a Discworld novel than The Colour of Magic. I laughed and I thoroughly enjoyed myself. While I’m still no die-hard fan of the books, I understand the euphoria better now and I’ll definitely will go on reading (you hear, deadra? Please bring me Men At Arms the next time we’ll see each other! And if you bought it in the meantime, you can also bring me Mort. Thanks).

G!G! has some great characters – Sam Vimes, of course, but also Sybil Ramkin and Carrot! And The Patrician is one of the coolest characters in literature ever, btw.

The story was funny, but nothing special. What makes these books readworthy is definitely the characters and the background stuff – the details, the footnotes, the way the Discworld functions.

And I lovedlovedloved the French and Latin [like “per say” or “Pour encourjay lays ortras”]. And there are very many quotable passages, which is also always a plus. Like:

People who are rather more than six feet tall and nearly as broad across the shoulders often have uneventful journeys. People jump out at them from behind rocks then say things like, “Oh. Sorry. I thought you were someone else.”

The three rules of the Librarians of Time and Space are: 1) Silence; 2) Books must be returned no later than the date last shown; and 3) Do not interfere with the nature of causality.

A number of religions in Ankh-Morpork still practiced human sacrifice, except that they didn’t really need to practice any more because they had got so good at it.

Altogether, I think it’s a book that grows on you as you gradually forget that there a few a bit boring parts and only remember the funny stuff. And there’s a lot of that, so that won’t be much of a problem.
