Death! — companion of the skyways and champion of the War — has descended upon the Master Spy with all the grim fury of a monster's hate! What are three men against the forces of hell itself! What price will brave men pay for their honor? The action is fierce, fast and frightening as we hearken to the Wings of Invisible Doom! G-8 and his Battle Aces rode the nostalgia boom ten years after World War I ended. These high-flying exploits were tall tales of a World War that might have been, featuring monster bats, German zombies, wolf-men, harpies, Martians, and even tentacled floating monsters. Most of these monstrosities were the work of Germany's seemingly endless supply of mad scientists, chief of whom was G-8's recurring Nemesis, Herr Doktor Krueger.
