I went to a talk or rather a Q/A session of his a few semesters back at my college. I definitely need to read that book at some point. In fact, I probably need to read more current literature as a whole. The most recent book I've read recently is actually Lolita
I was really impressed with it. I also remember having to make a concerted effort to read more current fiction when I was in school, as it wasn't easy at times. I also decided to focus my MA thesis on a then still living author, Saul Bellow, even though his work had never been assigned in a class.
I'd also recommend Cormac McCarthy, but only if you want to be immersed in, at times, a devastatingly effective incredibly bleak world view.
All the Pretty Horses is probably the lightest, but I've never forgotten a cauterizing a wound passage.
Blood Meridian is probably the darkest, even just for having quite possibly the most evil antagonist in literature.
There's also David Foster Wallace, with a much different writing style and varied quite a bit on whether he was writing an essay or news article, short story or epic novel. If you want a small dose, you may want to check out
The Girl with Curious Hair, a short story collection.
But I definitely recommend reading Diaz's
Oscar Wao, especially as he has an interesting approach I'd not really seen before. Nothing like stream of consciousness, but rather that of an intense story-teller of a narrator.
