The Echelon - Spy Girl, #7

Can one girl save the world? The Echelon's plan to change the shape of the world is succeeding. The disease was released. People are dying. Montrovia is surrounded. The Americans have declared martial law, stripping its people of their rights. And the world is in chaos. Huntley has always been willing to sacrifice herself for the mission, but what she wasn't prepared for is those she loves doing the same.
Can Huntley stop what started in Montrovia, or is it too late to save anyone?
