Captain Jay McCaulay can look after herself, but now she's no longer in the army she's turned complacent. She's been with TRACE, an aid agency, for two years, helping track and unite families separated by conflict, and her old job with the Paras seems very far away. Until she spots someone from her past. It is a past that involves Zamira, a beautiful young girl who Jay saved from being killed in Kosovo - a past that clashes with the present when Milot Dusmanic, an organised crime boss from Macedonia, appears on the streets of Bristol. Jay is a linguist. Her specialist knowledge as a soldier and translator means she is perfect for an MI6 mission to find out why Milot is in the UK. Jay doesn't want the job, but since her relationship with Detective Inspector Tom Sutton isn't going anywhere unless she chooses to commit, she seeks refuge in the mission. When she hears Zamira has vanished from her home in Macedonia, possibly trafficked into the UK - Jay's mission becomes personal. Thrown into a world that inspires paranoia, where brutal Mafia thugs give no quarter, and where her family and loved ones are threatened, Jay is forced to fight to confront a trail of murder, corruption and evil that has entwined itself from Eastern Europe into the heart of her home country, or risk losing everything she has ever held dear.
