Heroines - how far can she go?

Happy Hump Day everyone!! Now, as I am busily writing book number eight I had a sudden thought about this heroine of mine.

However, some of the story is set in the past, when she was 17. And back then she did something quite bad. Obviously I can't tell you what it was because that would spoil the whole book BUT what I want to know is...what will a rea...
