State of War: The Secret History of the CIA and the Bush Administration by James Risen, a review from Esquire by Anna Godbersen.
"In December of last year, James Risen was one of two New York Times reporters to break the story of the National Security Agency's vast, unprecedented, and, depending on your political point of view, illegal domestic spying program. His new book State of War fills in the back story and future prospects of the Bush administration's fraught (to understate the situation) relationship with intelligence. Risen places the NSA's warrant-less espionage (the agency is now 'eavesdropping on as many as five hundred people in the United States at any given time,' he writes) within the larger story of a CIA in decline."
