W. E. B. Griffin Rogue Asset by Andrews & Wilson by Brian Andrews

The secretary of state has been kidnapped by Islamic extremists and his only hope for survival is a reconstituted Presidential Agent team in this revival of W. E. B. Griffin's New York Times bestselling series.
Secretary of State Frank Malone has been kidnapped from his Cairo hotel-his security detail wiped out. President Natalie Cohen is left with several unacceptable options. It's time to think outside the box, and that can only mean one thing: the revival of the Presidential Agent program.
Cohen calls for Charley Castillo to come out of retirement to direct a new Presidential Agent, one Captain P. K. "Pick" McCoy, USMC. Charley may be too old to kick down doors and take names, but Killer McCoy is just the man to get the job done.
Together, they will track the kidnapped secretary from Cairo to sub-Saharan Africa. The only problem is that one man can't hope to win against an army of terrorists...good thing there are two of them.
