Now he's been called in on a solo mission--and the fate of the United States of America is on his shoulders alone. The mission: Prevent a presidential assassination by infiltrating the White House and locating the enemy operative. And when everything goes wrong, Ben must rely on his spy school friends to save his reputation... but even friends can double-cross or be swayed to the enemy's side.
