"Snow Crash" by Neil Stephenson.

"Ender's Game" and "Speaker for the Dead" by O.S.Card.

Asimov's original "Foundation" - it's effectively a collection of 4,5 short stories. I recommend to remain at a discreet distance from the rest of the series.

"Stranger in a Strange Land" by Heinlein. Not the easiest read

I forgot "Hyperion" by Dan Simmons.

"Rendez-vouz with Rama" by Arthur C. Clarke.

"Ender's Game" and "Speaker for the Dead" by O.S.Card.

"Embassytown" by China Mieville.
