Final Draft

I got the final proof of my book today. It's that last chance to edit, correct, or change the content. When I turn it in this time, I'll have a printed book within about two weeks.
This has been a very interesting process. During the initial submission, I went over columns with a fine tooth comb and corrected what I thought was all the errors. I had a friend go behind me just to make sure I had caught everything. He found additional mistakes that had slipped by. I was surprised.
When I got the first draft of the book printed last week, I had my nephew James go over the manuscript and he found even more errors. I couldn't believe it, but when I looked at the little squiggle marks, it was hard to dispute.
I've got a day or two to take one last look in search of the elusive error. I really wish I had paid more attention in English class.
