I need more of them. I recently finished Jonathan Franzen's "Freedom", which is a perfect example. Before that, there was Chabon's "The Amazing Adventures of Kavalier & Clay", and just the other day Don DeLillo's "White Noise."
Anyone have some good suggestions? I'm just starting Pynchon's "Against the Day" so I have a while before I start something else, but I'd love to have a list ready.
