The Girl With Acrylic Eyes. The Sophont Trilogy, #1

Coppélia is just a robot. Or is she? The year is 2103. Detective Inspector Karen Chambers arrives at NewMet City's SVU to interview a potential sexual assault victim. The call to attend surprised Karen as she's head of the Sexdroid Unit and usually deals with crimes such as misappropriation of sexbots, unregistered sexbot use, and kindbot misuse (kindbot use is strictly controlled and for psychotherapy purposes only). Imagine Karen's surprise when she discovers that the alleged abuse victim, Coppélia, is indeed an android, but her behaviour is totally unheard of in the world of robotics law enforcement.
Coppélia is completely different from any android that Karen has ever seen. The DI knows she should return Coppélia to her owner, but she also senses that there's more to Coppélia than meets the eye. Her detective instincts have been alerted. An out of this world discovery and a burgeoning friendship lead Karen to see Coppélia in a whole new light and question the relationship that humans have with their sapient androids.
