NSA director Theodore Anders has a simple goal: collect every phone call, email, and keystroke tapped on the Internet. He knows unlimited surveillance is the only way to keep America safe. Evelyn Gallagher doesn't care much about any of that. She just wants to keep her head down and manage the NSA's camera network and facial recognition program so she can afford private school for her deaf son, Dash.

A Secret Service agent is dead, an apparent suicide. A presidential candidate narrowly escapes an assassin's bullet. And Desk Three, a covert branch of the NSA, is searching for a chilling connection deep inside the Republic of Vietnam.

Once, Charlie Dean was a Marine sniper in Quang Nam Province. Today he's a Deep Black operator, and he comes face to face with a man he once hunted down...and thought he had killed.

Now, with every asset, weapon, bug and high-tech magic wand Desk Three can wave, the agents enter a terrifying global race against time.
