Rodney Morales
Rodney Morales is an American fiction writer, editor, literary scholar, musician, and Professor in the Creative Writing Program of the Department of English at the University of Hawaii. In both his creative and critical writing, he is concerned with contemporary multi-ethnic Hawaii society, particularly social relations between its residents of Native Hawaiian, Japanese, Caucasian, and Puerto Rican descent; the 1970s "Hawaiian Renaissance" movement and the disappearance of its legendary cultural icon George Helm of Protect Kaho'olawe Ohana (PKO); and the postmodern juxtaposition of popular artistic forms (the detective novel, cinema, crime fiction, rock music) with high literature. Shaped by genre fiction of the postwar period, his regional stories influenced that of Generation X/millennial authors such as Chris McKinney and Alexei Melnick, "urban Honolulu" novelists known for their gritty, realistic approaches to depicting crime, drugs, and lower-class life in the islands.
