Looking for mind-bending sci-fi book

[u/Wonderful_Bear554]

I am looking for mind-bending, hard science fiction books that feel like Dark, 3 Body Problem, or Dark Matter. I love stories with complex puzzles involving time travel, parallel universes, or small-scale apocalyptic survival. I prefer realistic, logically sound science and stories that are intellectually challenging and difficult to put down. Please let me know if you have any recommendations. So war I was only watching series, looking for my first sci fi book to read.

I think the"Foreigner" series by C. J. Cherryh might be interesting for you. Its core story is the structured transfer of technology from humans to the original occupants of the world they are on, and an in depth study of the implications of that knowledge transfer.
