silly "post race" claim here. Instead, what I'm indicating is that Whitehead and his book possess what's known as crossover appeal.
Some of the recent mentions of Zone One:
June 20 - The New York Times: "It [World War Z] does not expand the tonal range of zombie fantasy, like Ruben Fleischer's 'Zombieland' or Colson Whitehead's novel 'Zone One.'"
June 21 -- The Daily Beast: "Clear incursions have been launched over the literary barricades by Colson Whitehead’s Zone One, Rick Moody’s Four Fingers of Death, and Cormac McCarthy’s The Road (post-apocalyptic cannibals taken as nearly synonymous). They even got Jane Austen."
June 21 - Nerdist: "In comparison to other, more intelligent zombie fare like The Walking Dead, Colson Whitehead’s Zone One, or even Ruben Fleischer’s Zombieland, director Marc Forster [director of World War Z] takes a bit of a step back."
June 21 - Tor: "Colson Whitehead usually writes books that fall firmly in the 'literary fiction' aisle, but with Zone One he takes his beautiful way with prose and applies it to a post-post-zombocalypse story."
June 24 - The Washington Post: "Bennett Sims’s brand new 'A Questionable Shape,' may be the smartest zombie novel since Colson Whitehead’s 'Zone One' (2011)."
June 24 - Scholars and Rogues: "In a trailer scene reminiscent of Colson Whitehead's poignant Zone One (Anchor, 2011), zombies overrun an enormous wall."
