Whitehead has since produced seven book-length works—six novels and a meditation on life in Manhattan in the style of E.B. White's famous essay Here Is New York. The novels are 1999's The Intuitionist, 2001's John Henry Days, 2003's The Colossus of New York, 2006's Apex Hides the Hurt, 2009's Sag Harbor, 2011's Zone One, a New York Times Bestseller; and 2016's The Underground Railroad, which earned a National Book Award for Fiction.[5][6] Esquire magazine named The Intuitionist the best first novel of the year, and GQ called it one of the "novels of the millennium."[7] Novelist John Updike, reviewing The Intuitionist in The New Yorker, called Whitehead "ambitious," "scintillating," and "strikingly original," adding, "The young African-American writer to watch may well be a thirty-one-year-old Harvard graduate with the vivid name of Colson Whitehead."[7]
