Reddit, can you recommend some good sci-fi books?

I like books with settings in the mid to far future, with good scientific basis. Stories with clear good guys and bad guys, doesn't have to be epic. Nothing that deals heavily with pre-industrial or low tech aliens please(did not like "A Fire Upon the Deep"). Also no magics, or anything involving humanity facing extincting due to natural causes. A good story is always a plus. I am looking for pleasure reading.

Thank you.
