Any good stuff.

What I've read and liked:
Fear & Loathing in Las Vegas - One of the funniest books ever
Da Vinci Code - Just finished, impressive but not quite as amazing as I expected due to all the praise.
Some fantasy-novels by Margaret Weis
Harry Potter of course

catcher in the rye, j. d. salinger
the old man and the sea, hemingway
a farewell to arms, hemingway
catch-22, joseph heller
death of a salesman, arthur miller
the communist manifesto, marx & engels
thus spoke zarathustra, nietzsche

Angels and Demons
Dante's Inferno
Feed
Tom Clancy Books

Just look around, like New York's best-sellers usually have a few good ones on it.
