Empire of Lies 

Sustained by a deep religious faith, Jason Harrow has built a stable family and become a pillar of principle and patriotism in the Midwest. Then the phone rings, and his past is on the other end of the line. A woman with whom he once shared a life of violence and desire claims her daughter is missing – and Jason is the one man who can find her. Returning to New York, Jason finds himself entangled in a murderous conspiracy only he can see and only he can stop. Hunted by terrorists and by the police, Harrow has just hours to unravel an ex-lover’s lies and face the unbearable truth: in order to prevent a savage attack on his country, he’s going to have to risk his decency, his sanity, and his life.
