Looking to pick up a few more lines! Here are some ideas:
A black-market bounty hunter has been hired to kidnap the son/daughter of an international crime lord to bring to their rival for ransom. After a sudden hit of morality (or a revelation of a certain truth? dun dun dun), he/she decides not to carry on with the mission.
Or maybe something between a bodyguard and their grumpy/wayward protectee?
Mafia themed, perhaps?
Looking for het (as female), or slash! With guns, angst, fighting and smut in-between!
