Years ago, I bought my husband a special edition of To Kill a Mockingbird, which I inscribed, "To my own Atticus Finch." If you, like I, have spent most of your life believing that Atticus Finch was the greatest father, lawyer and most honest and decent man ever written, do not read Go Set a Watchman. There are some things you can't "un-know" once you know them, and you will never be able to look at Atticus Finch the same way again.
Maybe it was naive to believe that even a fictional character could live up to the ideals of Atticus Finch, and maybe this flawed version is still worthy of love, but I wish I never read this book. I wish I didn't know what I now know. I hate cliches, but this is one case where ignorance truly is bliss.
