Working Titles

I asked Karen Joy Fowler about her newest novel BOOTH. Here's what she said. "BOOTH was the working title. I imagined my editor and agents would want a new one, but they didn't; they thought BOOTH was strong. The issue for me was always that it gave the impression the book is about John Wilkes, but he was not the only Booth so it still seems fair."
And I'm still thinking about working titles.
