For two years, Donna McLean lived a life of bliss with her boyfriend, Carlo. But her great love story wasn't just built on lies - it was one. Because Carlo wasn't a bike-obsessed Italian locksmith at all; he was a British police officer, part of a unit that had worked undercover for years to infiltrate activist groups across the country.

More than twenty of those officers deliberately targeted women and duped them into relationships, posing as socialists, environmental campaigners and union reps, before vanishing without a trace. Small Town Girl is Donna's shattering story of a life turned upside down overnight, and her reclamation of a truth that was shamelessly buried by those who should be protecting the most vulnerable in society.
