I received my proof copy from Lightning Source today. It looks and feels nice

You of course are right Kang. I will need to resubmit the interior for a correction. One of the spacing for the chapter headers is off. Its a tiny thing, but easily correctable. Chapter 7 has 3 line breaks instead of 2 like the others. I used half inch margins and added a 1/8 in the gutter. That seems all worked out well.

I think I will take the rest of the week to thumb through it and let my editors do the same over the weekend before submitting changes and ordering a new proof copy.
