The use of so many readers worked quite well overall. I was a bit off-put by the inability of some readers to pronounce Swiss place-names — a reader who’s narrating the actions of a character who lives in Zurich should be able to handle “Strasse” and “Kirche” and the like.
The growling reader with the Scottish (?) accent who narrated the chapters of Socratic dialogue was also a bit hard to understand.
But overall an interesting experiment in audiobooking.
