Alt text:
I've been working my way through this 1950s podcast by someone named John Tolkien called 'Lord of the Rings'--it's a deep dive into this fictional world he created. Good stuff, really bingeable!
Kindle has this, it's called Whispersync. Of course you need to buy both the book and the audiobook so it's not cheap.
