Title: The Fifth Elephant
Author: Terry Pratchett
What it's about: The dwarfs are crowning a new Low King, and Lord Vetinari is sending the Duke of Ankh-Morpork to Überwald for the coronation. Vimes is not happy about this, but he goes, taking with him two of his officers, both natives of Überwald. He was also supposed to take Angua, but no one's seen her. This has Carrot so worried that he leaves the city and sets out to find her. Vimes, however, has bigger things to worry about than a missing officer. He has to put his policing skills to work to uncover a conspiracy involving an ancient dwarven artifact before everything devolves into chaos.
What I thought: I much liked the darker tone this book has, and the Überwald is an interesting place in contrast to Ankh-Morpork. I liked the parts Lady Sybil had in this book, like her knowledge of dwarven culture and her diplomacy, in contrast with Vimes' cruder ways. The parts with Angua and Carrot were kinda cute, too. The various plotlines intersected in just the right way, and the parts back in Ankh-Morpork with Colon were just right for keeping the book from getting too heavy.
Overall: Probably my favorite City Watch book, overall.
