The Director — David Ignatius

Graham Weber has been the director of the CIA for less than a week when a Swiss kid in a dirty T-shirt walks into the American consulate in Hamburg and says the agency has been hacked, and he has a list of agents' names to prove it. This is the moment a CIA director most dreads. Like the new world of cyber-espionage from which it's drawn, The Director is a maze of double dealing, about a world where everything is written in zeroes and ones―and nothing can be trusted.
