What I love about train journeys is the way every passenger can impact our lives, or at least make the time pass quickly. Every day, thousands of us board trains, some journeys short, some long, some destinations happy, some dreaded. We could find ourselves sitting next to anyone, talking about anything. Every carriage is a riot of possibilities in the usually humdrum routine of life, and if we're lucky we can leave with the warmth of a comforting word, an incredible story, camaraderie ... even romance. And on that very unusual day, it struck me how different my fellow passengers all were, so varied in appearance and manner and backstory - so it seemed all the stranger that the same theme came up time and again. Was it one of those things that cuts across all of humanity? But, of course, humans aren't the only players in this tale - and sometimes fate has other destinations in mind for us. No Boundaries is a tale of laughter, love and sadness, but also one of discovery - of places, people, spiritualism, and most importantly of ourselves.
