Across the globe, an American passenger airliner is shot down over Egypt-apparently by an Iranian missile-leaving the world wondering if it was an accident or an act of aggression. A massive global team lead by Soraya Moore is assembled to investigate the attack before the situation escalates.
When Bourne’s search for his would-be assassin intersects with Soraya’s search for the group behind the airplane bombing, Bourne is thrust into a race to prevent a new world war. But it may already be too late.

Now, these two trusted friends are on a deadly collision course. From the Colombian highlands to Munich, Cadiz, and Damascus, the clock is counting down to a disaster that will cripple America’s economic and military future. Only Bourne and Karpov have a chance to avert the catastrophe-but if they destroy each other first, that chance will be gone forever.

The trail will lead him through layers of conspiracy to a vicious Russian mercenary, Leonid Arkadin, who was also a graduate of the Central Intelligence training program Treadstone. A covert course designed to create ruthless assassins for C.I., it was shuttered by Congress for corruption. Yet before it was dismantled, it produced Bourne and Arkadin, giving them equal skills, equal force, and equal cunning.

As Bourne’s destiny circles closer to Arkadin’s, it becomes clear that the eventual collision of these men is not of their own making. Someone else has been watching and manipulating them. Someone who wants to know, Who is the more deadly agent?

The organization, the Black Legion, and its lethal plot have also popped up on the radar of Central Intelligence, where new director Veronica Hart is struggling to assert her authority. Sensing an opportunity to take control of CI by showing Hart’s incompetence, National Security Agency operatives plan to accomplish what CI never could-hunt down and kill Bourne.

In Europe, Bourne’s investigation into the Black Legion turns into one of the deadliest and most tangled operations of his double life-the pursuit of the leader of a murderous terrorist group with roots in the darkest days of World War II-all while an assassin as brilliant and damaged as himself is getting closer by the minute . .

To succeed, the real Jason Bourne must maneuver through the dangerous labyrinth of international espionage—an exotic world filled with CIA plots, turncoat agents, and ever-shifting alliances—all the while hoping to find the truth behind his haunted memories and the answers to his own fragmented past. This time there are two Bournes—and one must die.
