The battle for Earth is on!It was not an invasion from space. It was four invasions - simultaneous but each task force led by an Adamite naval commander and a beautiful dark-haired girl. It's the girls, Tomi, Verne, Gilen, and Pariss, who count most of all in the balance of power. For they are the Cosmic Spies. Earth slept through the opening moves of the game. But when they awoke, battle was finally joined between the two great races of Man.
To prove which was human.
