I'm not sure it totally fits, but Always Coming Home by Ursula K LeGuin was an amazing read. The premise is that an ethnographer of the future is writing about a future, post climate change California people called the Kesh. Most of the book is actually stories the Kesh themselves tell, be it poetry, folk tales, an autobiography, and even a snippet from a novel.
It's an absolutely transformative book that I can't recommend it enough. It's like nothing else I've ever read.
Learn how to run hexcrawl adventures for D&D 5e - includes an introductory hexcrawl, Langden Mire, for Levels 1-4
This is the hexcrawl ruleset that I've been basing a lot of my game rules on. Specifically I use it as a reference for it's Travel and Navigation rules, The Exploring Day, Resources, and Weather. I really like how it handles weather and have actually created my own weather tables that vary by season for the campaign setting I've got.
The vibe I'm going for is a hunter-gatherer/mythic setting, so lots of strange magical phenomena, ecology, wilderness survival stuff. I'm using this along with restricting long rests during travel to provide a sense of attrition.
