Matt and Emerald are coworkers, partners, best friends in the cutthroat Harmony syndicate. Emerald's life is so covered in blood that her teeth are stained with it, but she is an assassin. Matt's gotten out of more meetings alive than he hasn't, which he counts as a win. They're taking life one day at a time, together. An episodic, disordered view of the (mis)adventures of a stubborn, insensitive assassin and an easy-going, smooth-talking negotiator.
