"I have one rule, Robyn; no killing." "Way to take the fun out of it." "I'm serious, Robyn, no killing." "Not even a little bit?" "No." "Seriously? What if our lives are in danger?" "No killing." "Ugh, fine." *** In normal everyday life, Robyn Blake works as the personal assistant to Bruce Wayne-the billionaire by day, vigilante by night-and yes, she is aware. The whole reason she moved to Gotham was to get close to the man who killed her father, Ra's Al Ghul, but not for the reason you think. She was always taught to push down her emotions, so in everyday life-outside of a few select people-she is cold and calculating, her only release comes from her nightly activities as the new vigilante in town. However, her activities-and particularly, the fact that she doesn't mind dropping bodies-attract the attention of the one and only Batman. When these two unstoppable forces collide in their personal, professional, and secret lives, will Robyn be able to complete her mission and uphold her vow?
