Working my way through Discworld for the first time. Just finished listening to Witches Abroad and enjoyed that a lot, though the previous Reaper Man story spoke to me a little more. Small Gods looks to be next, which I've seen people speak highly of, so I'm looking forward to starting that.
Life on the Disc has been such fun to read about! I'm a bit sad I never got around to reading these sooner, but then again, it's been a real highlight of this year.
