Well, I thought wrong.
Here's the crazy part -- the main character's name is "Brooke." My mom (my biggest helper/editor, who's also read this book at least six times, carefully, for me) caught something in her sixth reading -- the name "Rachel." It was in a piece of dialogue between the main character and another character (not named Rachel): "Yadda yadda yadda," said Rachel.
My mom stopped, showed it to me, and said, "Umm, who's Rachel?"
As often as both of us had read the manuscript, we'd never caught that MAJOR mistake until that read-through. Rachel must've been my original name for the Brooke character three years ago (or, I had just watched an episode of "Friends" before I wrote that scene). My eagle-eyed agent also caught the mistake, before we had caught it. Oops. I hope he chuckled instead of winced, lol.
Anyway, it all goes to show that, even as many times as a manuscript is read, it still needs to be RE-read. Slowly. Carefully. Painstakingly. Many, many times over. And, by different pairs of eyes.
Because, somewhere along the way, you might just have a "Rachel" embedded in there. Sneaky wench. :-P
