Hogfather, if you can't tell from the fact I said "Christmas read", is Terry Pratchett's Discworld Version of Christmas. Now that I've stated the obvious, let's get on to the story. In Hogfather, the Hogfather has disappeared and Death has taken over his role. This disturbs his granddaughter Susan so much that she starts investigating what happened.
Obviously I love this novel. As I do all Discworld books. I have read Mort but this is the first time I've read a book that starred Susan. The fact that she was the Duchess of Sto Helit gave me pause and got me to feverishly google why she was the duchess and Death's granddaughter. But Susan is an awesome character. She's practical and good with kids, which means that she's not a normal hero. She's as undramatic as possible.
Plus, the Unseen University faculty play a fairly major role. Ridcully and his new bathroom, Ponder Stibbons, and even a new machine called Hex.
Oh, what am I saying. This is a Discworld novel. My words can't praise it enough. You should go read it, and then watch the two-part series (which I'm watching right now).
