On a routine intelligence gathering mission in Tehran, Jack Ryan, Jr., has lunch with his oldest friend, Seth Gregory, an engineer overseeing a transcontinental railway project. As they part, Seth gives Jack a key, along with a perplexing message.

The next day Jack is summoned to an apartment where two men claim Seth has disappeared—gone to ground with funds for a vital intelligence operation.  Jack's oldest friend has turned, they insist.

They leave Jack with a warning:  If you hear from Seth Gregory, call us immediately. And do not get involved.

But they don't know Jack. He won't abandon a friend in need. 

His pursuit of the truth will lead him across Iran, through the war-torn Caucasus, and finally deep into territory coveted by the increasingly aggressive Russian Federation. Along the way, Jack is joined by Seth's primary agent, Ysabel, a enigmatic Iranian woman who seems to be his only clue to Seth's whereabouts. 

Jack soon finds himself lost in a maze of intrigue, lies, and betrayal where no one is who they seem to be—not even Seth, who's harboring a secret of his own that harkens back to the Cold War. A secret that is driving him to the brink of treachery.

Racing against the clock, Jack must unravel the mystery: Who is friend and who is foe? Before it's over, Jack Ryan, Jr., may have to choose between his loyalty to Seth and his loyalty to America.

Former Army Ranger Tucker Wayne and his war dog Kane are thrust into a global conspiracy that threatens to shake the foundations of American democracy in this second exciting Sigma Force spinoff adventure from New York Times bestselling authors James Rollins and Grant Blackwood.

Tucker Wayne's past and his present collide when a former army colleague comes to him for help. She's on the run from brutal assassins hunting her and her son. To keep them safe, Tucker must discover who killed a brilliant young idealist—a crime that leads back to the most powerful figures in the U.S. government.

From the haunted ruins of a plantation in the deep South to the beachheads of a savage civil war in Trinidad, Tucker and Kane must discover the truth behind a mystery that leads back to World War II, to a true event that is even now changing the world . . . and will redefine what it means to be human.

With no one to trust, they will be forced to break the law, expose national secrets, and risk everything to stop a madman determined to control the future of modern warfare for his own diabolical ends. But can Tucker and Kane withstand a force so indomitable that it threatens our very future?
