There's a stage few people talk about between the worst days of an eating disorder and full recovery. It's the messy and misunderstood middle. That's where author and professor Mallary Tenore Tarpley finds herself as an adult who spent her teenage years in and out of hospitals with anorexia. In her new book, she blends her own story with insights from hundreds of patients worldwide and the doctors working to better understand this space, where setbacks are real but so is progress. Her book is called Slip: Life in the Middle of Eating Disorder Recovery.
