Yes ! I started with Go Set a Watchman two days back ! My notes so far (I am a little less than halfway through):
1. There's no one cooler than Scout. Atticus maybe. But no one cusses like Scout.
2. Jem. Well, that hurt on page 13.
3. Jem, Scout and Dill as kids again. Oh the fun !
4. Aunt Alexandra. And her corsets.
Nothing substantial has happened so far, which is OK by me. Reading about Maycomb is like going back to my childhood. Nothing beats that.
