Thud is the latest of Terry Pratchett's Discworld novels (#30). The Discworld novels come in several flavors: there are wizard books, witch books, DEATH books, "the guard" books, and there are one-offs (like The Truth and Moving Pictures.) The books all take place on the Discworld, but the different "flavors" are the story settings/characters. Some of the books include more than one flavor--witches and wizards, witches and Wee Free Men, wizards and luggage made of sapient pearwood, guards and vampires, etc. Anyway, Thud is a book about The Guard, and the lead character is Commander Vimes.
Commander Vimes has come a long way since the earlier Guard books. He has a wife, a small son Sam, and a lifetime of policing to help him along. In
Thud, Vimes has the job of trying to prevent an all out war between the dwarves and the trolls.
Since there are dwarves and trolls among the guard, Vimes is in a good position to know how the two interact. While Vimes is investigating a murder, he is distracted by a new officer (a female vampire--albeit one who has "taken the pledge" to eschew blood drinking) and an efficiency expert sent by Lord Vetinari. There also seems to be some sort of demon lurking about, there's a big painting missing from the museum, and the anniversary of the battle of Koom Valley (a battle between dwarves and trolls) is fast approaching.
As is often the case with Discworld novels--there are echoes of our world in the goings on in the Discworld. There are "deep" dwarves (fundamentalists) telling the city dwarves they need to return to their traditional ways. There is scripture (of a sort) and scriptural interpretation on which an outbreak of war may hinge. And then there is the watch, and politics, and budgets, and equal employment opportunity (for vampires.)
As is
always the casein a Discworld novel, there is lots of fun to be had and plenty of silliness to consider along the way to the neat wrapping up of the plot.
Thud is neither the funniest nor the most inventive of the Discworld novels, but it is must reading for Pratchett fans, and good fun for those new to the series. If you're really new to the series, though--I'd recommend you start with one of the earlier books to get some background on the Discworld. Two of my favorite recent entries in the series are
Hat Full of Sky and
The Wee Free Men.
The Color of Magic is the first book in the series (and features the hilarious sapient pearwood "Luggage". You can find a full list of the Discworld novels and lots more Pratchett info on the web. Here are a couple of useful sites:
