Long wait til next Christmas

Tradition has it I get a new Terry Pratchett book each Christmas. I read it non stop until finished, usually before New Year. Then I immediately re-read it slowly, picking up all the little jokes, the links to previous books and the puns. Second time round I really appreciate his writing.
All well and got but I have now finished Raising Steam, book 40 in the Discworld series. So maybe I will have to did out one of the previous Christmas presents and re-re-read it. If the weather carries on like it is I could be re-re-reading a lot of old Christmas presents
