Books you can't traditionally read

I've recently been working on Ursula K Le Guin's "Always Coming Home" and have never experienced a novel like this. Instead of a traditional narrative, Ursula has used an anthropological journal/ survey of a fictional, future tribe of humanity to drill in on her ongoing question/ theme of, "What kind of world do you want to live in?" Or at least, that's the question she always seems to be evoking in her literature.

So, have you read or come across this sort of novel before? Where traditional use of narrative is actively eschewed or presented via different means? I'm not looking for suggestions on what's similar to Always Coming Home, instead just if you've had a non-traditional novel cross your path, and what did you make of it?
