"I received a wonderful email after I spoke at a school from a girl who'd lived in a war zone and endured horrors no human being should suffer, let alone a child. This young lady was fortunate to be bought to Britain and seemed to adjust well, but suddenly found herself falling off the rails and sliding into hell when I chatted to her. In her letter, she told me the difference that I'd made. She's now 20 years old and a fashion designer employing staff and she puts her work ethic down purely to talking to me. It's my most treasured letter."
