Dominican-American novelist Junot Diaz published “The Brief and Wondrous Life of Oscar Wao” a decade ago. The book won the Pulitzer Prize for Fiction in 2007. When he’s not writing, he teaches college students--he formerly taught Freedom University here in Georgia, which offers post-secondary education to undocumented immigrants. We speak with Junot Diaz ahead of a lecture at Emory University at 7:30 p.m. on Wednesday, April 12th.
