An old enemy resurfaces. A new threat is born. There's been no sign of Nexus since Loveday and her team captured his hired thief in St. Petersburg, but the Ivory Tower Spies are on high alert. There's no telling what havok Nexus will wreak once he learns how to leverage the facial recognition software he stole. But then the bodies start appearing, just as they did nearly twenty years ago. Loveday and her team find themselves in a race against an old enemy. Their objective? Break into the CIA and secure the agency's undercover agent files before Nexus does. Because if they fail, more agents will pay with their lives. And one of their own is on the top of the enemy's hit list.
