The Phoenix Code by Catherine Asaro (Paperback)

Deadly awakeningWhen robotics expert Megan O'Flannery is offered the chance to direct MindSim's cutting-edge program to develop a self-aware android, it's the opportunity of a lifetime. But the project is trouble plagued--the third prototype killed itself, and the RS-4 is unstable. Megan will descend into MindSim's underground research lab in the Nevada desert, where she will be the sole human in contact with the RS-4, dubbed Aris. Programmed as part of a top-secret defense project, the awakening Aris quickly proves to be deviously resourceful and basically uncontrollable. When Megan enlists the help of Raj Sundaram, the quirky, internationally renowned robotics genius, the android develops a jealous hostility toward Raj--and a fixation on Megan. But soon she comes to realize that Raj may be an even greater danger--and that her life may depend on the choice she makes between the man she wants to trust and the android she created.
