I've been going through my "author proofs" on the homestretch to getting the book printed and my editor is very busy saving me from myself. I was an English major in college, but I must have slept through all the grammar stuff because the Chicago Manual of Style might as well be written in Russian because it's that foreign to me. I'm not really sure why tenses have to match anyway. And it's okay that I call a character by one name and then change their name later in the story. The reader can figure that out right?
Now I know why NO ONE should ever be self-published. You need a professional to save you from yourself. And Karl, you are my hero!
