Terry Pratchett is hilarious, his prose is excellent, and to top it off, he's a prolific author, so if you're like me and always running out of reading material, reading everything he's written should keep you busy for a while.
This particular comedy is (as you may be able to discern from the title) about vampires. Vampires and a girl named Agnes Nitt, who struggles sometimes to suppress her alternate personality, Perdita. To paraphrase a quote from Pratchett, "Inside every fat girl is a thin girl and a lot of chocolate." Agnes' alternate personality is explained by the fact that Perdita is the thin girl inside.
I love this book, it's good for an hour or two of laughs, and I've always been partial to the title. Carpe Jugulum=seize the throat, a play on Carpe Diem (seize the day) for anyone unfamiliar with the Latin. I recommend it to anyone who enjoys vampire comedy at its best.
