Sequel to To Kill a Mockingbird

"To Kill a Mockingbird" will not be Harper Lee's only published book after all. Publishing company Harper Collins  announced Tuesday that "Go Set a Watchman," a novel the Pulitzer Prize-winning author completed in the 1950s and put aside, will be released July 14. Rediscovered last fall, "Go Set a Watchman" is essentially a sequel to "To Kill a Mockingbird," although it was finished earlier.
