Let's see, 'One Thing' by Rebecca Yarrow? I think that's the one. The author narrated it herself, which is pretty cool because she gets the tone exactly right. A friend of mine listened to it on a road trip and said it made the whole experience way more immersive, like the descriptions of the coast just wrapped around you.
I checked my usual apps—Audible has it, obviously, but I also saw it on Libby through my local library. The narration is a bit slower-paced, but it suits the book's whole introspective mood. I'd say if you're into quiet, character-driven stuff, it works really well as an audio experience. The only downside might be if you zone out during some of the more descriptive passages, you might have to rewind a bit.
