Ignatius, David - Free Library Land Online

In David Ignatius's gripping new novel, spies don't bother to steal information…they change it, permanently and invisibly.
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.
Weber turns to a charismatic (and unstable) young man named James Morris who runs the Internet Operations Center. He's the CIA's in-house geek. Weber launches Morris on a mole hunt unlike anything in spy fiction—one that takes the reader into the hacker underground of Europe and America and ends up in a landscape of paranoia and betrayal. Like the new world of cyber-espionage from which it's drawn, The Director is a maze of deception and double dealing, about a world where everything is written in zeroes and ones and nothing can be trusted. The CIA has belatedly discovered that this is not your father’s Cold War, and Weber must play catch-up, against the clock and an unknown enemy, in a game he does not yet understand.
