I just finished reading “The Art of Discworld” by Terry Pratchett and Paul Kidby. I liked it quite a lot, mostly because I like reading about how authors think of their own work, or tell about how their ideas grew or mutated or just plain changed.
Back in the day when I used to read Piers Anthony’s books it got to the point where I didn’t enjoy the story as much as I enjoyed Mr Anthony’s author’s notes in the back.
Rarely, it seems, do authors write about the genesis of their works and tag it onto the beginning or end for their readers to enjoy, and I think that’s a shame. It’s understandable, though.
