Alpha by Catherine Asaro
The creator of a proscribed network of rogue Als and androids has been destroyed, his multiple copies deleted. Except for one. Alpha: a female android who seems to possess a conscience - so much so that her execution is delayed. Big mistake. Now, on the run, and with her former captor as hostage, Alpha moves to activate a long dormant master-plan - a plan that may well include the end of humanity and the violent transformation of the world as we know it!
