When leading actress Sienna Vale becomes trapped in a devastating defamation case, special investigator Jack Kovar is sent to Hollywood to uncover the truth. What begins with accusations, ruined reputations, and carefully constructed lies leads Jack toward connections that should not exist—and people determined to make certain he never discovers why.

The FBI fears something worse: an attack on the United States. As old adversaries emerge and a once-in-a-generation Arctic cold front bears down on the country, Jack finds himself caught between an investigation he cannot abandon and the very system he has spent his career trying to protect. Someone is preparing for what happens when the lights go out, and Jack is beginning to suspect the power grid was never the real target. The Constitution is.
