The book is about a teenage girl whose life is forever changed by the tragic accident that leaves her taking the identity of a supermodel, Nikki Howard.

Em tries to remember the events that led to her current state and finds out that not only did she die during the accident, Nikki had collapsed from a brain aneurysm at the same time.

In an effort to save Em, her parents agreed to a controversial brain transplant offered by Stark Industries, transplanting her brain into Nikki's body, on the condition that Em continues Nikki's career as the face of Stark Industries; the penalty for breaching this contract would be two million dollars.

Although she is now dealing with Nikki's job, friends, and various boyfriends, she fights to keep some of her old life by going back to school and facing Christopher, whom she has a secret crush on.

When Em notices that Christopher is now a mess because of her supposed death, she goes out of her way to talk to him, and try to make him realize that she is still alive in someone else's body.
