Assassins have eliminated a Chechen scientist who's been working as a double agent for the U.S. government. The feds know who to call: Jonathan Grave and his elite rescue team. Their mission: find the dead man's teenage son, who's on the run-and off the grid-with crucial information that must not fall into the wrong hands. There's one problem: the boy's bodyguard is a security specialist with unusual talents, and she's not giving up without a fight. Only by bringing them both back alive can Grave expose the traitor in the highest levels of power-and prevent an all-out nuclear war.
