Younger African-American novelists include David Anthony Durham, Karen E. Quinones Miller, Tayari Jones, Kalisha Buckhanon, Mat Johnson, ZZ Packer and Colson Whitehead, to name a few. African-American literature has also crossed over to genre fiction. A pioneer in this area is Chester Himes, who in the 1950s and '60s wrote a series of pulp fiction detective novels featuring "Coffin" Ed Johnson and "Gravedigger" Jones, two New York City police detectives. Himes paved the way for the later crime novels of Walter Mosley and Hugh Holton. African Americans are also represented in the genres of science fiction, fantasy and horror, with Samuel R. Delany, Octavia E. Butler, Steven Barnes, Tananarive Due, Robert Fleming, Brandon Massey, Charles R. Saunders, John Ridley, John M. Faucette, Sheree Thomas and Nalo Hopkinson being just a few of the well-known authors.
