Revenge of the Nerd

Amanda Storm was your stereotypical nerd, but with one slight difference. She was practically oozing wealth, but she already had enough people treating her like a fragile, priceless piece of art. She spent her life at school dressing down as much as possible, trying not to be treated any differently.
And that's exactly what she got.
Every day, she would be bullied by the populars. The populars turned all of her friends against her, and pitted them against one another.
Finally, Amanda decides to take a year abroad.
When she returns, she's no longer the nerd that got pushed around. She's the rich girl who decided to be bad.
And the most popular guy in school definitely takes notice.
