Invasion, defection—and a last stand to save Earth. Dissident alien commander Arid Ricimer and his human allies, Captain Jim Coalbridge and Lieutenant Commander Griff Leher, are the courageous and very mortal heroes who must face down the forces of a tyrannical star empire. Captain Arid Ricimer, an alien starship commander with integrity and a clever plan, attempts to defect to Earth with his officers and entire spaceship—a vessel that mounts a superweapon of almost unimaginable power. He's pursued by his former fleet, a force that has already devastated Earth once and is poised to wipe humanity from existence forever. In a thriller filled with echoes of The Hunt for Red October and cool hard science fiction technology, it's a desperate gambit for the alien captain and for humanity, as well. Yet after years of battling back from the brink of destruction, the U.S. space navy has the wartested heroes to rise to the challenge, among them attack ship captain Jim Coalbridge and alien analyst, Griff Leher. The players are in motion and the greatest confrontation this sector of the galaxy has ever witnessed is at hand. All depends on the courage of an honorable alien warrior and the intelligence and daring of his human counterparts and would-be compatriots.
