@brianokken What kind of sci-fi do you like? Do you want super hard sci-fi (Diaspora by Greg Egan is great, as are most of his books, including Permutation City)? Military type sci-fi on the more rompy side it would be hard to go wrong with the Vorkosigan Saga.

Rainbows End is also great if you haven't read it. As are many things by Ursula Leguin, especially The Dispossessed.

I have several dozen more recommendations of various quality if you want.
