Stolen Eyes: Book 2 of The Nanobot Wars

Earth is taken. Women are almost extinct. Bianca, the twisted, feminine AI, has infected every mind. Survivors retreat to a space station, where scientists develop a powerful, short range weapon. Bianca slips from one body to the next, so finding her is impossible. But she'll show up to take sixteen-year-old Jackie, the only host who won't sicken and die if she gets infected. The admiral wants Jackie to return to Earth as bait, but if she sets off the device, the blast could age her 75 years in an instant. Jackie refuses. Then Bianca's nanobots sabotage the station. It won't stay in orbit much longer. Jackie takes off with the device, prepared to sacrifice herself. She doesn't count on being followed by the guy who loves her.
