It’s hard to think of what to say except… this is my favorite book so far. It touched me deeply, both as a human being and as someone whose natural default state is 'walking existential crisis'. It’s one of my favorite books in general, forget placing it in just a Discworld hierarchy.
I found this quote of Terry Pratchett writing about the character Death:
"Occasionally I get letters from people who know they are due to meet him soon and hope I’ve got him right. These are the kind of letters that cause me to stare at the wall for some time…"
Yes, I feel the same way.
