Jack Ryan
Tom Clancy Executive Power

When an American intelligence team on a routine mission in Angola is wiped out, the sole survivor is Kyle Ryan, youngest son of President Jack Ryan. But this massacre is the prelude to an even more devastating conflict - a deadly military coup. In a shocking escalation, the American embassy is seized and hostages taken, including the ambassador and the younger Ryan. As U.S. forces fight insurgents street by street, Lieutenant Katie Ryan leads the effort to untangle the mystery behind the Angolan coup and the identity of the plotters, while President Jack Ryan and his National Intelligence Team anxiously await answers.
The full executive power of the presidency is useless if they can't find the target. Kyle and his fellow hostages sit at the center of the bull's-eye. Jack Ryan has faced many challenges as president, but solving this problem is no one-man job. It's going to take all three of them to get through this.

An international incident may fracture the Ryan family in the latest entry in this #1 New York Times bestselling series.
