To Kill a Mockingbird is a much-loved story about two young children coming of age in the American South, a region wracked by racial conflict and injustice during much of the 20th century. Fans were thrilled when a follow-up novel by author Harper Lee was released. But in Go Set a Watchman, readers were dismayed to find that a beloved and honorable character in the first book had transformed into an unapologetic racist in his later years. This twist forces the reader to confront the character’s evolving beliefs, as well as their own.
