Purge is a beautifully crafted memoir that has a Girl, Interrupted feel. In this raw and engaging account of her months in rehab, Nicole Johns documents her stay in a residential treatment facility for eating disorders. Her prose is lucid and vivid, as she seamlessly switches verb tenses and moves through time. She unearths several important themes: body image and sexuality, sexual assault and relationships, and the struggle to piece together one's path in life. While other books about eating disorders and treatment may sugarcoat the harsh realities of living with and recovering from an eating.
