Sometimes it's helpful to be the "mouth" in "word of mouth." I took my book with me to a couple of places in town. One of those places was the gas station near my house. I stop there several times a week, and the clerks know me by face. It's the bane and the benefit of living in a small town.
I held out my book and said, "See? I wrote a book."
She asked if she could look at it and I handed it to her. She flipped through several pages and eyeballed the description on the back with a smile on her face. "This sound good!" Her eyes hardened, though still twinkling, as she looked at me over the top of her glasses. "You wrote this? Really?"
I assured her I did.
She looked it over, trying to find my picture. Mental note made: put a photo on future books. Her eyes locked on mine and she asked again with different emphasis: "You wrote this?"
Pause. "Show me your I.D."
She was impressed...as soon as she matched the name on my driver's license with the name on the book. I'm starting to like this author thing...
