What I Lost by Alexandra Ballard is about Sixteen-year-old Elizabeth who has honed a dangerous skill: starving herself. Even when her parents send her to a treatment center for her eating disorder, she can't stop. Then she begins receiving packages from someone she doesn't know. Is it a secret admirer, or someone playing a cruel trick? In the end, Elizabeth determines the identity of the gift-giver-it's someone totally unexpected, whose intentions are good. And, even more important, she finds a way to play an active role in her recovery.
