No one wants the duty of policing the violent miners and cyborgs that populate the territory. No one except Luisa who has dreamed of being a police officer since she was young. But this cop isn't your regular law enforcement agent. She's a hardnosed fighter who pulls no punches in Kieron Gillen's original sci-fi epic!
