Book excerpt: What sixteen-year-old Elizabeth has lost so far: forty pounds, four jean sizes, a boyfriend, and her peace of mind. As a result, she’s finally a size zero. She’s also the newest resident at Wallingfield, a treatment center for girls like her—girls with eating disorders. Elizabeth is determined to endure the program so she can go back home, where she plans to start restricting her food intake again.She’s pretty sure her mom, who has her own size-zero obsession, needs treatment as much as she does. Maybe even more. Then Elizabeth begins receiving mysterious packages. Are they from her ex-boyfriend, a secret admirer, or someone playing a cruel trick? This eloquent debut novel rings with authenticity as it follows Elizabeth’s journey to taking an active role in her recovery, hoping to get back all that she lost.
