Top 10 lists are highly subjective, and the fact that he doesn't include some classic authors doesn't mean he never read them...

Well that was a bit harsh. Of course, it never hurts to get acquinted with Hemingway, Faulkner et al., but it's not like Don Quixote should be everyone's favourite novel or anything. Just because it's a classic doesn't necessarily mean that it resonates with you. And this is coming from someone who reads a lot, prefers older stuff and studies literature at the university.

Anyway, here's my list. I picked novels (and novellas!) that have made the biggest impact on me and that I've enjoyed rereading over the years. And since I got a little stumped after I'd thought of nine novels, I decided to bend the rules a little and include a graphic novel. Sorry. :) Not in order of preference, that would be way too hard.

Post Office by Charles Bukowski
The Stranger by Albert Camus
Heart of Darkness by Joseph Conrad
Brothers Karamazov by Fedor Dostoyevsky
Steppenwolf by Herman Hesse
Ulysses by James Joyce
Metamorphosis by Franz Kafka
The Bell Jar by Sylvia Plath
Fight Club by Chuck Palahniuk

+ Watchmen by Alan Moore & Dave Gibbons

LOL - there'd be some people disappointed with my list, then. I don't read to be well-versed in classic literature; I read to be entertained and to spark my imagination. Maybe it's shallow but I don't care to spend time slogging through something that I don't enjoy. I mean, I bought The Odyssey a while back and it just about killed me getting through the damn thing. Okay, it's a classic. I get it. I also couldn't stand it. Right afterward I read Snow Crash, thoroughly enjoyable, and it would probably make it on my top ten along with some other non-classic fiction.

I can't really make a top 10, but so far, I LOVE every books of Haruki Murakami I read up to now!
And I also love the books of Boris Vian I read so far.

And people, stop to be snob about art. Everyone has the right to love anything, be it a "classic" or newer / more mainstream art. And people can love a painting or classical music (for example) without knowing all the meanings / vocabulary bullshit people talk as if this art could be appreciated only by the elite. And if I love something, I don't care if it's the subject of thesis in universities.

My... how literary everyone is. Reading such clever books and all. I couldn't care less about those so called classics, so for variety I'll provide my list.
