#1 New York Times bestselling author Brad Thor thrills with his new summer blockbuster starring Scot Harvath.

A devastating series of bombings tears through Bangkok. Scores of American citizens are dead. The attacks send shock waves around the world.

As global assistance pours into Thailand including the FBI s famed Evidence Response Team the president of the United States quietly prepares a plan B: Scot Harvath, America s top spy, trained to operate outside the law and probe the dark corners others can t or won t.

But the bomber Harvath is pursuing isn t a terrorist. He s something far more dangerous one of ours.

Meanwhile, in Washington, a former United States Marine is being hunted and he has no idea why. Desperate for answers, he turns to the one person he still trusts his exfianc e, a rising star in the White House. The problem is, she isn t sure she can trust him.

As Harvath closes in on the bomber, a devastating truth begins to emerge. China has quietly deployed its most elite intelligence unit to Thailand. Their objective: to ignite chaos, trigger a military coup, and seize control of a narrow but critical piece of land, one that could give Beijing a decisive advantage.

If the plan succeeds, Beijing will secure a key gateway between two oceans, eroding American naval dominance and tipping the balance in any war between the world s great powers.

China will control the ultimate geopolitical choke point.
