A lot has been written on Junot Díaz lately.  For several weeks starting in September, he appeared in at least twelve publications that showed up at my house.  He was in everything from the unsolicited Time Magazine, apparently intended for my fifteen-year-old son, to Vogue, where Díaz appeared in costume, dressed as a member of Edith Wharton’s circle.  Díaz’s face smiled out from Entertainment Weekly, and he appealed for understanding from the pages of the New York Times Magazine. Online, the Guardian Blog stated that the term “genius” was inadequate praise.  Seemingly everywhere, his big glasses, smooth head, trim beard, and tentative smile greeted me. If Andy Warhol still lived, he would use Junot Diaz as a subject.
