Gamora, Captain Marvel, Amadeus Cho, Darkhawk, Cosmic Ghost Rider! Five unlikely operatives recruited by Maximus of the Inhumans. Their mission? Protect the delicate balance of new Galactic Union by ANY means necessary... and failure is NOT an option. Expendable, deniable and disavowed, they are the Imperial Guardians. But can they do Maximus' dirty work and keep their consciences clean? Why has a Kree Grand Admiral gone rogue and attacked Hala? What's going on with Darkhawk's mind? What deluded fool thought COSMIC GHOST RIDER was a team player? And, most importantly... what kind of game is Maximus REALLY playing?
