For more than two decades, Kevin Briggs lived the kind of life where the smallest details could quite literally be the difference between survival and death. He met hundreds of people in their darkest hours, chased to the edge of one of the world's most popular suicide destinations by demons their closest friends often didn't know about. Talk softly, and slowly. As their names, and if they have children. Talk about hope, but make no false promises. Kevin has helped more than 200 people find a reason to keep living. He's lost only two. These are his stories.
