Premise
"A novice U.S. Secretary of State joins the administration of her rival, a president inaugurated after four years of American leadership that shrank from the world stage. A series of terrorist attacks throws the global order into disarray, and the Secretary is tasked with assembling a team to unravel the deadly conspiracy, a scheme carefully designed to take advantage of an American government dangerously out of touch and out of power in the places where it counts the most."
