The DOP chip sits in Artemisia Lindsay’s brain, its tiny wires reaching through her cortex to fix the connections her own autistic neurons failed to make on their own. Artemisia can function in the human world, even if she's still just as logical, honest, and intense as she was before the computer in her head started managing her hyperactive senses. The one thing the DOP doesn't fix is the essential detachment she feels from the rest of humanity. It takes a police detective named Mike Tyler to do that. When she's called to the scene of a kidnapping to help Mike find another DOP, a remote device attempts to rewrite her software. Although it nearly kills her, Artemisia’s sudden ability to see smells and heat, to control the senses that tortured her as a girl, makes it clear that the reprogramming has been gloriously successful. And it's the only clue they have to track down her attacker.  An attacker who has kidnapped his first, failed, victim to study and who now knows his potentially fatal experiment can succeed under the right circumstances.  He just needs more data points, and there are several hundred DOPs.    Unfortunately for him, Artemisia Lindsay, with her usual single-mindedness and considerable intellect, is going to find him and stop him. Even if it means sacrificing everything to do it.
