Marko asks for a good reason to read the Discworld books by Terry Pratchett. Here is the comment I left.
I don't know if I can clearly explain it, but I'll try.
doesn't write in a conventional "serious" mode. Therefore, his
descriptions of things: people, places, ideas, attitudes (many of these
being fantastical things), are not constrained by the limits of "serious"
writing. His humorous fantasy style allows him to slip outside the
usual methods of description, and takes the reader outside of the
conventional methods of understanding.
Even if he is only describing a wet rock, you will see it in a new and different way.
That's my take on it.
