Captured by Mitch Rapp, ISIS's top technology expert reveals that he was about to meet a man who could bring down America's power grid. When the CIA trap to eliminate this man fails, ISIS operatives help the cyber terrorist do what he said he would - plunge the country into darkness.
With no concept of how this unprecedented act was accomplished, the task of getting the power back on could take months, or even years. Computers and phone networks are down, petrol pumps are inoperable, even water systems and food supplies are struggling.
With resources suddenly gone and America on the brink of collapse, Rapp and his team embark on a mission to find the only people who can repair the damage - the ones who caused it.
But this is unlike anything he's experienced before and time is running out...
Can Rapp get the lights back on before it's too late?
