Mom says karma always comes around to get you, and I guess it's true. Because last summer I was a total liar, and now, right in the middle of Mr. Pritchard's third-period math class, my whole world is about to come crashing down.

That's because while Devon was living with her grandmother for the summer, she told her "summer friend," Lexi, that she was really popular back home and dating Jared Bentley, only the most popular guy at school. Harmless lies, right? Wrong. Not when Lexi is standing at the front of Devon's class, having just moved to Devon's town. Uh-oh.

Devon knows there's only one way to handle this — she'll just have to become popular! But how is Devon supposed to accomplish that when she's never even talked to Jared, much less dated him?! And it seems the more Devon tries to keep up her "image," the more things go wrong. Her family thinks she's nuts, her best friend won't speak to her, and, as if it's not all complicated enough, Jared starts crushing on Lexi and Devon starts crushing on Jared's best friend, Luke. It all has Devon wondering — who is the real Devon Delaney?

Harriet Manners knows a lot of things. She knows that a cat has 32 muscles in each ear, a "jiffy" lasts 1/100th of a second, and the average person laughs 15 times per day. What she isn't quite so sure about is why nobody at school seems to like her very much.

So when she's spotted by a top model agent, Harriet grabs the chance to reinvent herself. Even if it means stealing her Best Friend's dream, incurring the wrath of her arch enemy Alexa, and repeatedly humiliating herself in front of the impossibly handsome supermodel Nick. Even if it means lying to the people she loves.

As Harriet veers from one couture disaster to the next with the help of her overly enthusiastic father and her uber-geeky stalker, Toby, she begins to realise that the world of fashion doesn't seem to like her any more than the real world did. And as her old life starts to fall apart, the question is: will Harriet be able to transform herself before she ruins everything?
