Scooch over, Nathan Zuckerman. New Jersey has bred a new literary bad boy and his name is Yunior. A Dominican immigrant with a fondness for women and weed and wordplay (in roughly that order), Yunior is the mostly decent, commitment-shy alter ego of novelist Junot Díaz who grew up about a half hour south of Newark, the boyhood home of Zuckerman creator Philip Roth.
