Alastair Reynolds's Revelation Space series is fantastic and sounds like what you're looking for.

I'm as in the dark as you are, but I think part of the complaint is that

1 Lemmy.ml still federates with lemmygrad.

2. Lemmy.ml and lemmygrad seem to be hosted on the same machine.

This looks great! I'm going to pick this up as soon as they release the VR version, so like 2027ish.

Lemmy was my first fediverse app. I i joined ages ago, then eventually went back to reddit because usage was so low. Then later I joined mastodon after Twitter imploded. And now I'm back on Lemmy. There are people here now! It's great!
