Is Harper Lee’s “Go Set A Watchman” A Sequel, Or What? The Publisher Explains

Jonathan Burnham of HarperCollins: “It’s set 20 years after the events of To Kill a Mockingbird, … during the mid-1950s during a turbulent time in American racial politics. … In a way, it’s a pre-sequel, if that could exist. None of the material from Go Set A Watchman can be found in To Kill A Mockingbird. All the scenes are new. The writing is new. … It’s in every respect a different novel.”
