Okay so this is a big deal
To me, and to a significant subset of Sir Terry's fans (including most of you who've found this by the tags), his writing is serious commentary on the human condition - politics, prejudice, self-control, revenge vs. justice, religion, idealism, faith in people vs. cynicism, and more - dressed up with fantasy settings and a hefty leavening of humor to make it fun to read. And it is WILDLY fun to read, actual laugh-out-loud or at least a snicker averaging about every page.
But there's this common idea among the "important literature" people that fun and funny books are not also worthwhile or important in the same way.
This is a Discworld book being released WITH ACADEMIC COMMENTARY and AS A PENGUIN CLASSIC. That's a HUGE amount of recognition.
Oh, I’m about to tear up. I had to fight so hard to do my thesis on Pratchett because the university didn't like what they considered pop culture being studied as literature and this is just... Existing. 🥹
