Harper Lee is publishing a follow-up to To Kill a Mockingbird (which is not exactly a follow-up, as it was written prior to that book.) Everyone in the universe is super-excited. With good reason! 88 years old and Lee has never before risked a sophomore effort. You have to imagine she wouldn't have decided to put this out there unless it was really good.
I have to say, however, that she's not doing herself any favors with that odd title. Go Set a Watchmen. Huh. Does not make a lot of sense to me. I think she kind of missed the boat here. It's not too late. The book doesn't come out for months; she can still re-think that title.
You have a genuine American Classic to build off of, why not take advantage? You want something that throws the first book in the reader's face; something that clubs them over the head with the fact that this is another book about Scout, who they goddamn LOVED in the original.
Here, then, to help Ms. Lee, is a list of titles I think might grab the reading public a little more firmly by the balls:
To Kill Another Mockingbird
To Kill a Mockingbird II: Mock Harder
To Kill a Mockingbird II: Scout's Honor
To Kill a Mockingbird II: Atticus Attacks
To Kill a Mockingbird II: Revenge of Boo Radley
To Kill a Mockingjay (brings in the YA crowd with one simple change)
To Kill a Pelican
To Kill a Penguin
To Kill a Myna Bird
To Kill a Motherfucker (kind of a hard-R version)
To Kill a Mockingbird and Then Go After His Family
2 Kill a Mockingbird
2 Mockingbirds, 2 Furious
To Text a Mockingbird
To Tweet a Mockingbird
To PM a Mockingbird for Details
To List a Mockingbird on Craigslist
