Dark in the City (Gotham fanfic)

Red is Gotham's newest member who meets the wrong people. But she's hiding something, something that could make the villains of the city win over the heroes

This story is set toward the end of season 1 and onward.

All credit goes to the creators of Batman, his villains and the lovely people who created Gotham the TV show.
Rated M for strong language and some possible sexuality. Definitely violence later-ish into the story.
