The Ghost in the Doll. Fox Meridian, #6

Fox has undergone a pretty big change in her life. For one thing, her batteries need charging each night, but her confidence has taken a hit too. When you're questioning the choices you've made, a good way to start is at the beginning. Fox returns to Topeka where people are dying due to faulty implanted organs. Meanwhile, Yuriko Fukui has been looking into a potential case of corporate espionage concerning one of MarTech's subsidiaries, BioTek Microtechnologies.
Someone has beaten them to market with the world's first bioroid, an artificially manufactured, biological entity. The 'Ghost Dolls' are strange beings: beautiful women with plastic skin and far beyond the technology their manufacturers are thought to possess. Yuriko quickly finds herself at odds with her brother, the leader of the most powerful yakuza organisation in Japan. When Fox joins Yuriko on the case, they soon uncover the truth behind the Ghost Dolls, and it's something far more horrific than the selling of corporate secrets.
