Olivia Hawthorne

During the summer, Kelly's mom tells her that she is dating a new man and they're taking a family vacation. As it turned out, the man her mother was dating was the father of the evil twins.
When their parents married her mother, the twins picked on her more, constantly teasing their new stepsister.
Three days after her eighteenth birthday, and on Homecoming night, an event happens that changes everything between them and Kelly learns that there's more to the twins than meets the eye.
