I would just suggest anyone interested read Atomised. The Possibility of an Island and Platform were excellent as well but not quite as earth shattering. Haven't gotten to the new one yet.
I'm reading Public Enemies right now; it's a correspondence between Houllebecq and French left wing intellectual Bernard Henri Levy. They don't debate so much as humorously compare ideologies, reminisce and examine how their upbringings contributed to their current views.
