It's been twenty years since 9/11, two decades since the United States was attacked on home soil and set out to make the guilty pay with their lives. In the shadows, the enemy has been patient--learning, and adapting. And the enemy is ready to strike again. A new president offers hope to a country weary of conflict. He's a young, popular, self-made visionary ... but he's also a man with a secret. Halfway across the globe a regional superpower struggles with sanctions imposed by the United States and her European allies, a country whose ancient religion spawned a group of ruthless assassins. Faced with internal dissent and extrajudicial targeted killings by the United States and Israel, the Supreme Leader puts a plan in motion to defeat the most powerful nation on earth. Meanwhile, a young PhD student has gained access to a bioweapon thought to be confined to a classified military laboratory known only to a select number of officials. A second-generation agent, he has been assigned a mission that will bring his adopted homeland to its knees.
