Carpe Jugulum
by Terry Pratchett (Doubleday, 1998)
audiobook read by Nigel Planer (Isis, 2000)
A perfectly respectable Discworld novel. The vampires pose a serious threat; Agnes Nitt evinces personality(ies). Still, there are rather more characters than focus, and thus a nagging sense of Pratchett extemporising a skyscraper and pulling it into place at the pointy end.
