The latest book by Pulitzer Prize-winning author Junot Díaz, This Is How You Lose Her, is a collection of stories linked by recurring characters. Last month, it was nominated for a National Book Award. Less than two weeks later, Diaz won a coveted MacArthur "genius" grant (half-a-million dollars over five years). He also teaches writing at MIT. Several years ago, after the release of his celebrated novel, The Brief Wondrous of Oscar Wao, he was the toast of the Miami Book Fair Interational.
