Abducted across the galaxy by aliens, collared and forced to serve as concubine, escape is not possible. My only hope lies with Cesar, my pirate lover. But can he buy me out of slavery if the Cats won't sell? Cesar did his best to negotiate my sale, to buy me out of service as concubine to Captain Cronin of the Gran. The Captain refuses to bargain. Once more, I'm forced across the galaxy, to the opulent palace of the Emperor, kneeling to serve the sexual demands of an alien Cat. In my absence, the adolescent Prince has reached maturity, and now he wants me for his own, to be his mate - over the Captain's dead body. Will I ever be freed of these damned Cats and their perverse desires?

My name is Angel, and I've been abducted and stolen across the galaxy by the Gran, a fierce race of alien cats. The captain of the Gran knows my secrets - I'm the product of illegal genome experiments to perfect the human race. He exploits my special qualities when I serve as his concubine. When I'm not serving the captain, I fulfill his wishes. He ordered me to breed or die, so I breed, constantly. Or I try to. Jason, my fellow captive and lover, is my anchor to sanity. Unfortunately, Jason doesn't know my secrets. He considers clones an abomination. I fear the day my lover helps us escape as he's promised. I fear his rejection if he learns of my deceit. I pray to a universe that has never shown me favor. I pray our love can survive our escape. The series: Born of illegal experimentation on the human genome, I've been taken for a ride across the galaxy, enslaved to the warlike race of cats called the Gran. They think I'm some kind of upgrade, a new slave stock to be bred. Though many would resent me for the decisions I have made, they never experienced my struggle to find love and meaning in a world where I do not belong. A freak of nature, the humans don't want me. Far more valuable than they could ever know, the cats don't appreciate me. Trapped in the conflict between two galactic empires, the pirates can't save me. Thrust into the center of an interstellar war, the Earth Defense Council never saw me coming. I am Angel 6.0, and this is the dark, wicked, violent tale of my life.
