Poltergeist: The Renascence City Chronicles, Book 2 (Unabridged‪)‬

Tracy Night had her life stolen in a single moment. Now she has a decision to make: 1. float into the warm and welcoming light above her, or 2. step into the light emanating from the robot she has been working on for the past four years. One offers her eternal piece and happiness for the rest of her existence; the other, vengeance. 

Hell hath no fury like a woman scorned.
