Books in the Tomorrow's Angels series

Mayfair Electronics has created life. But four of their Special Editions--sentient androids indistinguishable from human--have escaped. Rebel, Christian Aguillard and his owner, March, are on the run, but they have a bigger problem than his creator's plan to destroy him. They've discovered that one of the renegades has suffered a dangerous malfunction, threatening them with more than just exposure. Trapped on a cruise ship in the middle of the Atlantic, March and Christian must stop the insane robot before someone else dies. All the evidence points to March being the killer's next victim.
