I have a couple of new ideas I'm toying with.
I got this idea from remembering Where in the World is Carmen Sandiego? [sigh, yeah, I'm a nerd]. Basically, it'd be a crime-thriller. I have the idea of the female character being a world-renowned thief, charlatan, scammer and basically baddy; doing everything to take ppl's money and treasures. My character would be the Interpol agent assigned to capture her. There might be some backstory between them, if you pm me, we can work that out.
More to be added later...
