The Omcri Matrix — Jay D. Blakeney

In the Planet Patrol, Costa was the best. The smartest, toughest, most ambitious officer in the ranks. Until the day the Omcri-a deadly alien force of faceless assassins-kidnapped the Kublai of Drugh, killing Costa's patrol but leaving her alive. The brass think Costa has sold out. And now she's on the run, desperately trying to clear her name. Her search for the truth will lead her from the back alleys of her own planet to the savage dangers of unknown worlds-and finally, into the dark heart of the Omcri Matrix.
