So I got her email address from my editor and sent her a note about it being a small world.
It's even smaller than I imagined. It turns out she also copyedited Torched. Which was from a completely different house - Putnam vs. Henry Holt. She even remembered the old title, which was "Fire, Kiss, Electric Chair." [Full disclosure: And Girl, Stolen used to be Shadows Walking Backward.]
Small world indeed.
