Harriet Manners knows a lot of things. She knows that a cat has 32 muscles in each ear, that a "jiffy" lasts 1/100 of a second, and that the average person laughs 15 times a day. However, what she isn't so sure about is why it seems like nobody particularly likes her at school. When she is discovered by a top model agent, Harriet seizes the opportunity to reinvent herself. Even if it means stealing her best friend's dream, incurring the wrath of her arch-nemesis Alexa, and constantly embarrassing herself in front of the impossibly handsome supermodel Nick. Even if it means lying to the people she loves. As Harriet stumbles from one couture disaster to the next with the help of her overly enthusiastic father and her ultra-geeky stalker Toby, she begins to realize that the fashion world doesn't like her any more than the real world does. And as her old life starts to crumble, the question arises: Will Harriet be able to transform herself before she ruins everything?.
