In the latest addition to the acclaimed Pierce Hunt series, Hunt races across Europe to stop an ever-changing threat to national security before it's too late to save his country or his friends.

When the CIA calls on former Army Ranger Pierce Hunt to find a missing operative and friend, the last thing he wants to do is leave the peace of home and family behind. But there's more to this mission than meets the eye, and Hunt knows he has no choice but to risk everything to save his friend and protect his country.

Hunt's target is Jorge Ramirez, who allegedly has information that poses a threat to the national security of the United States. As Hunt tracks Ramirez in Switzerland, he learns that someone close to his operation has betrayed the CIA. His team is attacked, and not everyone makes it out alive.

Facing betrayal on an international scale, Hunt doesn't know who to trust. The rules of engagement have changed, and the body count is rising. Will he find out the truth in time, or will this be Hunt's final mission?
