Okay, I don't think I can really convincingly explain this, but I just about think DeLillo's books are perfect books to me.
Never a line out of place and always in a sort of a rhythm that keeps you reading. The characters seem ultra-real, certainly more than even King's sometimes, and they always have situations where they are constantly questioning, and in other case seeing everything as a satire in life. They feel important, just as much as the subject matter feels important.
Americana, his first novel, which I'm digging into now, reads so perfect it's almost unbelievable.
