At 11 years old, Alex Batty vanished on what was supposed to be a short family holiday with his mother and grandfather. An international missing persons investigation was launched, but years passed without a trace. Then, six years later, a teenager appeared on the side of a road in the French Pyrenees and told a passing driver that he'd been kidnapped. Alex, now aged 20, is ready to tell the full story about his abduction and his life on the run. For the first time, he retraces the route of his disappearance across Spain and France, uncovering not just how he was hidden but the belief system that kept him there. Each revelation builds a chilling picture of how easy it was for a child to disappear in plain sight.
