I am Katie Mitchell. I was 24 years old when I vanished on the Appalachian Trail.

My parents, Robert and Linda, never stopped searching. They never knew I was just a few feet from a busy road, hidden in plain sight.

This is my story.

The summer of 2005 was supposed to be the best time of my life. I had just graduated from college with a journalism degree, and before I settled into a career, I wanted to do something bold.
