Reluctant Supervillain

When Marcie fell for the straight girl at school and tried to kiss her, she thought that her life was over. But then, she went to Art's party. There is nothing like waking up in the bushes with a dead body and blood all over you to put things into perspective, especially when the cops show up minutes later. As Marcie still had no memory of what really happened, all she wanted was to get away from the party before she was arrested for murder.
It wasn't often that things played out the way that Marcie wanted, and that night was no exception. However, when Marcie is cornered in the kitchen, the truth about that party, and her blossoming powers, comes out in vivid details. Moreover, that she isn't alone in getting powers. That everyone at the party were getting them, including the straight girl, her new nemesis, Tracy. Yet when these powers are revealed to the world, who gets to choose which is the hero and which is the villain.
