With prose as spare as the meals her characters would prefer to be eating, Yana Zgheib delicately sketches the interior world of Anna, a ballerina undergoing inpatient treatment for anorexia. We hear Anna's ongoing battle of will and words with the disease and her treatment team, and watch her develop friendships with the other girls and spend visiting hours with her husband, Matthias. The "girls," you see, are young adult women -- eating disorders not being restricted to teenagers -- and that gives this story far greater impact. This disease is not something a patient will outgrow, although the reader dearly hopes Anna will. The Girls At 17 Swann Street won't make you an expert on anorexia, but as an intro to "Eating Disorders 101," it's a great place to start.
