The most important thing to know about The Brief Wondrous Life of Oscar Wao by Junot Diaz is that it is a MULTI language book. Large portions of it are written in Spanish. There are also numerous other phrases and situations lifted from a number of sci-fi books, anime, manga, which form a language in and of themselves. You either need to know all of these worlds thoroughly to understand the book, or you need to have a "cliff notes" guide next to you and go back and forth between the book you're reading and the explanation of what the chapter actually meant.
