Hopeless. Freak. Elephant. Pitiful. These are the words of Skinny, the vicious voice that lives inside 15-year-old Ever Davies's head. Skinny tells Ever all the dark thoughts her classmates have about her. Ever knows she weighs over 300 pounds, knows she'll probably never be loved, and Skinny makes sure she never forgets it.

But there is another voice: Ever's singing voice, which is beautiful but has been silenced by Skinny. Partly in the hopes of trying out for the school musical - and partly to try and save her own life - Ever decides to undergo a risky surgery that may help her lose weight and start over.

With the support of her best friend, Ever begins the uphill battle toward change. But demons, she finds, are not so easy to shake, not even as she sheds pounds. Because Skinny is still around. And Ever will have to confront that voice before she can truly find her own.
