Percy Weasley's twin sister, Elizabeth, was everything Percy was so thankful he was not. Percy was the perfect one; the prefect; the head boy. And Elizabeth? Well, she was the one in detention. Elizabeth was the prankster, the troublemaker, the rule breaker, and while that may have been Percy's worst nightmare, it's the thing that, when one of Elizabeth's reckless escapades goes too far and she finds herself trapped in time, catches the eye of the only person with a more troublemaking personality than Elizabeth herself, Sirius Black.
