They were the perfect family, and he was the perfect family man. But one day changed it all.

Arrested for racketeering, Ben Raab must testify against a Colombian drug cartel before leaving his lifestyle as a wealthy lawyer forever. He and his family will join the FBI's Witness Protection Programme. Currently protecting over 4,500 people, it is the most successful scheme of its kind ever, the backbone of American justice.

But the Programme's perfect success rate is about to come to a shocking end. Their case agent is found tortured to death, and then Ben suddenly vanishes. The only person who might be able to find him is his eldest daughter, Kate.

Covers blown, forced to question everything they know, the Raab family is plunged into a terrifying existence no one has prepared them for.

Most people would call it certain death.

The FBI calls it The Blue Zone.
