Cosmopolis by Don DeLillo
I read this book ages ago, in English, I didn't have the knowledge of the language then for it to make much sense. Read it again when it was announced to be a movie. It's still very much over my head, but the language in it is so mesmerizing you cannot help but to be pulled in and awed.
I have a thing for dialog heavy books, so this is right up my ally.
