Six secret operatives are the military’s top experts in covert ops and rescue missions. But this elite special force doesn’t exist - at least not in the public eye. No one knows where they come from or to where they return. The group gathers for the most dangerous, most difficult, and most important missions and often operates in extreme conditions. They are known only by their code name: Invisible Six. Special operative Shade is working out of the US embassy in Tek City, Tekistan, when fighting erupts between rebel and Tek government troops. The Americans are trapped in this rebellion, unless Invisible Six can escort them to safety. But the Tek government wants to take the American civilians as bargaining chips. Can Shade and I-6 help the civilians escape from Chaos City? Ages: 10 to 11
