You already know Greg Egan, so I would very much recommend Diaspora. Really amazing book. I wrote about it here: http://uzpg.me/literature/2019/04/29/diaspora.h

I wrote about it here: http://uzpg.me/literature/2019/04/29/diaspora.html http://uzpg.me/literature/2019/04/29/diaspora.html > (e.g. about facing a totally different culture). I would also recommend The Player games by Iain Banks. Not hardsf per-say but really nice and complex story.
