"When Mitch Rapp captures ISIS's top technology expert, he reveals he was on his waay to meet a man who claims to have the ability to bring down America's power grid. Rapp is determined to eliminate this shadowy figure, but the CIA's trap fails. The Agency is still trying to determine what went wrong when ISIS operatives help this cyber terrorist do what he said he could -- 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. Perhaps even years. Rapp and his team embark on a desperate search for the only people who know how to repair the damage -- the ones responsible. But his operating environment is like nothing he's experienced before. Computers and communication networks are down, fuel can no longer be pumped from gas stations, water and sanitation systems are on the brink of collapse, and the supply of food is running out. Can Rapp get the lights back on before America descends irretrievably into chaos?"-- Provided by publisher.
