In the Scottish Highlands, pathways cut through the magnificent sights. Pathways, strips of downtrodden mud. Trails. An old man walks one of those trails, every year. When he does, he struggles with his own history, every year. This year is different. A young woman follows him, also wants to walk a trail that is history. They meet, and end up in their own history of death, life, love and eternity. No names appear in TRAIL, just people. The reader is free to recognise and name their own trail, their own experience.
