Sooner or later, we all face a moment of truth. For Roscoe Cook, that moment arrives when he comes face-to-face with his own past, as the Cosmic Guard - the mightiest military force the Galaxy has ever seen - takes aim at his home, and everyone he loves. With its Interstellar Navy no more than a rag-tag collection of pleasure boats and a few rusty frigates, Planet Isis stands alone as the last bastion of human civilization untouched by the madness that has swept the rest of Humanity. Hated by half the galaxy, and denounced as a traitor from one end of Terra to the other, Admiral Cook is all that stands between Isis, and certain destruction. In the thrilling climax to the "Guardians of Peace "saga, Cook and a handful of brave Isitians make their desperate stand against Terra's invincible Cosmic Guard, with the future of the human race hanging in the balance.
