All Jenna Rink wants to be is pretty and popular. And on her thirteenth birthday, she gets her wish.

When she wakes up, Jenna is is stunned to eiscover that she's...a grown-up! Not only does she have an amazing apartment and a closet filled with designer clothes, she also has a high-powered magazine job, celebrity friends, and a knockout body!

But although she looks thirty on the outside, on the inside Jenna is still thirteen, and she has missed everything in between. And what's worse is that her grown-up self has made some bad decisions -- decisions that Jenna is determined to make right.

In over her head as an adult, Jenna needs to find the only person who can help her -- her best friend from childhood, Matt. He'll know what to do. But when she finds him, he's a grown-up too, and definitely not the same awkward teenager that she remembers.
