I download books from my library to my kindle. It goes through Amazon though, so I assume I am also impacted by this BS.

Be sure to check out your local library. Mine has a service where you send them examples of what you tend to like and they will send you a list of recommendations. Some of my favorite books have come from the list they gave me.

I’m currently reading this and am thoroughly enjoying it. However, I’m not sure how much it relates to the “alone in space” angle that OP is looking for.
