I’m currently reading a book called Shoeless Joe which is the book that inspired Field of Dreams. As a big baseball fan it was a must read for me, plus I wasn’t aware it was based on a book until a few years ago.
I finished the Little House books. Always wanted to read them and found them at a flea market. My grandmother loved the show and as a kid I didn’t care about it but as an adult I love it. Always at least a few episodes in my DVR.
In my own case, aforementioned friend gave me her amazon login so I can just listen to any of her purchased library, but that's the legal way. If you want to keep your access within the bounds of legality and proper respect for copyright, I hear you should by no means ever visit foul sites like 'audiobookbay' or similar. No sirree.
