Most Sci-Fi is Hellagay

There's only a handful of good sci-fi books the rest is escapist fantasy that would only appeal to the most sheltered sort of nerd who takes no solace in reality today.

I like Starship Troopers, Brave New World and Slaughterhouse Five.  All those books have strong sci-fi elements but are firmly grounded in reality.  If your the type of person that enjoys "Star Trek: Return from the Gamma Quadrant" then you are a fucking waste of flesh.

Are there any other sci-fi books out there that you think I might enjoy?
