The old maxim is true: you never begin writing until you begin rewriting and editing. In my case, I received edits and suggestions back from my agent, Dawn Dowdle. I worked through them and sent them over for her second review after Thanksgiving.
There truly is nothing like having an agent review every page, every comma (many misplaced) and every line of your book. I'm lucky, because not all agents put in the amount of effort to make a manuscript squeaky-clean. (And from many of the books I've read lately, the fine art of copy editing is dying.)
So, when I finished reviewing every change, answering every comment, adding a few comments of my own, I realized my manuscript is in much better shape than it was.
My eternal gratitude for Dawn's close review. After three critique groups had a go at the work, and two professional editors had their say...
And now we will see what additional changes Dawn suggests to make the manuscript marketable.
