When interrogator Emma Ripley learns of an imminent attack on US soil, she is not surprised. What does shock her is when the most valuable prisoner ever to arrive in custody is handed to her. Georges Subdallah is a US citizen, long ago radicalized, and the most skilled bombmaker in the world. He is a man long thought dead – the famous architect of his own horrific suicide bombing years ago. In him, Emma faces her most complex and urgent counterintelligence order: to extract key intel to stop the largest attack in US history. To do so, she must reach a man willing to die for his cause, who has sat maimed and broken these last years in a secret building. To prevent further bloodshed she must learn what made him turn against his country, what brought a model US citizen, with a wife and young daughter, to blow himself up.
