Claire Martin has some serious body issues.

Not much happens in Claire's sleepy beach town, but that's okay. All she wants is to hang out with her best friend, make the high school swim team, and convince Nate, the guy of her dreams, to stop calling her "Dude." And, oh—she'd really, really like to stay in her own skin.

Ever since Claire hit her teens, electrical storms have been making her switch bodies. Usually she's back to her old self in no time. But when something goes terribly wrong, she finds herself stuck as another girl. And not just any girl, but the icy beauty who has caught Nate's eye.

Suddenly Claire goes from being Miss Average to Miss Gorgeous—the model-thin blonde that every girl wants to look like and every guy wants to date. Will she ever figure out how to get back to her old life? More importantly, will she want to?
