Posting for Brendan’s birthday!
The Wind’s Twelve Quarters is by Ursula Le Guin—it’s a collection of earlier short stories from the first 10 years of her writing. I know Le Guin as a celebrated sci-fi/fantasy author who likes to explore deep philosophical ideas so I know this will be a good one once I get around to it! She also includes a foreword where she briefly mentions the inspiration for each story.
