Answer
"Go Set a Watchman" is an earlier draft of "To Kill a Mockingbird," written by Harper Lee. Originally intended to be her debut novel, it was significantly revised and published as "To Kill a Mockingbird" in 1960. While both works share characters and settings, "Go Set a Watchman" portrays a different perspective and presents a more complex portrayal of Atticus Finch, the moral center of "To Kill a Mockingbird."
