Extract: Countdown by James Patterson and Brendan DuBois
The CIA's highly classified Special Activities Division is in the business of tracking people down and keeping secrets hidden. Then a botched field operation reveals some dark dealings between an officer's superiors and an informant, including a plot that could kill thousands of Americans. Knowing that her leadership is corrupt to the core, she is forced to give up her identity and work from the shadows. But it's not easy staying hidden when your enemies are elite intelligence operatives.
