Book excerpt: Seventeen-year-old Elena is vanishing. Every day means renewed determination, so every day means fewer calories. This is the story of a girl whose armor against anxiety becomes artillery against herself as she battles on both sides of a lose-lose war in a struggle with anorexia. Told entirely from Elena's perspective over a five-year period and cowritten with her mother, award-winning author Clare B. Dunkle, Elena's memoir is a fascinating and intimate look at a deadly disease, and a must read for anyone who knows someone suffering from an eating disorder.
