Realms of Light

Private investigator Carlisle Hsing had escaped from doomed Nightside City, on the planet Epimetheus, to the neighboring planet Prometheus. She never intended to go back. But then a billionaire by the name of Yoshio Nakada decided she was the only one he could trust to investigate an assassination attempt, and offered her a deal she couldn't refuse -- a deal that took her back to Nightside City.
