Love the Orson Scott Card.
I vetoed the Hunger Games because it would freak him out. Can throw Fear and Loathing and Clockwork Orange in this group.
Fahrentheit 451 sucked. One of the very small handful of books that I started reading and did not finish.
Read the Road. Too dreary. No Country was good.
Was not crazy about the Martian Chronicles or any Vonnegut.
Will add Gatsby and Animal Farm to the list.
In that case I would remove The Handmaid's Tale (freaky) and World War Z (zombies). Even Ender's game is pretty freaky/violent at some points. I loved the Illustrated Man. It is a fun collection of short stories. The Natural and Pricess Bride are both really close to the movies but with definite improvements.
Some others are I loved but have turned off some of my friends are:
Red Mars Trilogy by Kim Stanley Robinson, hard sci-fi about colonizing Mars and years after.
World War books by Harry Turtledove. He does a lot of alt-history books. In this series lizard aliens invade Earth during WW2. Reread that last sentence and tell me you aren't intersted.
