Go Set a Watchman by Harper Lee.
Scout (Jean Louise Finch) returns to Maycomb from New York after the Supreme Court rules to desegregate schools and discovers that the town has changed beyond her comprehension.

So, I read To Kill a Mockingbird again earlier this year in anticipation of reading this book, which I ordered literally the day it was first available on Amazon.com. After the kerfuffle about it possibly being released against her will I considered canceling my order, but the truth is, from the moment I heard it was the book that eventually became To Kill a Mockingbird, I wanted very badly to read and see what the editor had seen. Unlike many people, I did not read Harper Lee's classic until I was an adult. In fact, it's been less than five years since I first read it. So I do not have a deep love of the book earned by reading it in school. In fact, I found it to be a shockingly racist read, both casually and overtly. Now, seeing the source material for it, I understand why.
Let's get this clear right off the bat: Go Set a Watchman is not a sequel to To Kill a Mockingbird, it's the raw source material that book was crafted from. It is not entirely the same universe... the reason Atticus took the case at the heart of To Kill a Mockingbird is different, as is the outcome of the trial. And all that is mentioned only in passing, not as the key events around which the story turns. This is not to be taken as some definitive version of To Kill a Mockingbird. Go Set a Watchman touches on some of the events in the earlier published book, but it is a completely different book with a different aim and perhaps even a different audience.
Lots of people have talked about the racism of Atticus in Go Set a Watchman. I was surprised to hear people complain about it, as it is definitely there, if only between the lines, in To Kill a Mockingbird. Atticus is a man of his times, and there is no possibility that a man of that age born and raised in that place is not racist. The same is true of Scout.

That said, it's clear to me why Lee's original editor suggested taking out the bits about Scout's childhood and forming a book around them. It was a brilliant way to tell about the people and the place without inserting a painful amount of heart-wrenching drama about what was then almost current events. And oddly, thanks to the original book being a classic, Go Set a Watchman has the potential to affect many readers almost as painfully as Jean Louise was affected in the book. Without that years-long set up, there's no way this book would be having the extreme impact it is.
I think To Kill a Mockingbird is undeniably a better book than Go Set a Watchman. I also think this is a very good time for the release of the original source material. People need to go back and reassess their assumptions - about Atticus, about Scout - about racism and family and what the world expects. I found it well worth reading, but your mileage may vary depending on how you feel about Lee's original work and especially how you feel about Atticus.
