Publisher Description

When a member of his Cabinet is killed in a plane, President Jack Ryan suspects that the "accident" is anything but in this latest shocking entry in this #1 New York Times bestselling series.

The White House is stunned when the Secretary of Commerce is killed in a plane crash in Turkey. President Jack Ryan isn't ready to write this off as a simple accident. Not only has he lost a good friend, but the Secretary was on an important mission: on the surface he was making an appearance at an economic conference, but the CIA was also using the flight as cover to extract an important asset from the Middle East.

Soon, Lt. Commander Katie Ryan and her team are working with the investigators to find the cause of the tragedy, but one shocking revelation changes everything. There were supposed to be 16 people on the plane, but there are only 15 bodies.

The quest for answers will lead the team deeper and deeper into a quagmire of lies and deception that will force President Ryan to face an unprincipled enemy with global ambitions.
