Are you happy, angry, confused, scared? Can this novel, her first and unpolished, possibly compete with or even simply add to the original?

Cast your stones here!Go Set a Watchman is a novel by Harper Lee, set to be published on July 14, 2015 by HarperCollins in the United States and Heinemann in the United Kingdom. It was written before her only published novel, To Kill a Mockingbird. The title comes from Isaiah 21:6: "For thus hath the Lord said unto me, Go, set a watchman, let him declare what he seeth." It alludes to Scout's view of her father, Atticus Finch, as the moral compass ("watchman") of Maycomb.
The novel follows an adult Scout Finch who travels from New York to Maycomb, Alabama, to visit her father, Atticus Finch, twenty years after the events of To Kill a Mockingbird. According to the publisher, Scout "is forced to grapple with issues both personal and political as she tries to understand her father's attitude toward society, and her own feelings about the place where she was born and spent her childhood." Go Set a Watchman includes many of the characters from To Kill a Mockingbird.
