I loved Diaz's short story collection Drown, and like almost everyone else who read it, have been eagerly waiting years for his next book. Now, something like a decade later, Diaz brings a character from that collection (Yunior) back to narrate the family history of his Rutgers roommate Oscar (who is also the brother of Yunior's sometime girlfriend). This tale begins with Oscar's grandfather and ends up encompassing quite a bit of the modern history of the Dominican Republic. And although the story hopscotches back and forth in time and location quite a bit, Diaz has complete command of his narrative.
