I read this book a few years ago and I can't remember the title of it. I remember that the story started off about the main character - a detective with a polish style last name. The time frame was in the near future. He was investigating the murder of his female partner - whom came back to life temporarily. The story also featured a female gladiatorial style street fighter that helped him destroy the "bad guys" at the end of the book.
I can even remember one fight of hers involving one of the android assassins that was trying to kill her and some important person's son:
I hit him with all I had, and I had a lot.
Living in the main character's building, was a psychic of sorts. She could see the auras or sigils of people, and rearrange them to change their moods. It was revealed in the novel that the killer of the female police officer was a common friend of her and the main character.
The book also featured several android/terminator type enemies that were hunting the cop down for his investigation. The female pit fighter, at the very end of the book, joined the military so she could earn a higher class of citizenship.
Any help would be appreciated. I sadly didn't own the book, I borrowed it from a coworker. I would like to read it again, but I just can't find out the name, nor can I remember it at all. Please advise.
