The author creates a world in words on a page. A voice artist gives audio life to those words and world through the "theatre of the mind." The very best of voice artists become invisible as you listen to the life they have created.
Close to 20 years ago, I took a job in a special library about an hour from my home. Long story short, the job was not what was it described as and it turned out to be a bad fit. I did learn a few things and one was the great pleasure of audio books.
I live in a city and haven't driven in a million years, so I only began listening to books when I figured out that I could do so while running. While slow of foot, I'm a speedy reader and have discovered that certain books work better than others, listening-wise.
