#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 ex-fiancée, 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.
