In Koppelman's new novel, Dr. Susanna Seliger is a renowned psychiatrist who specializes in treatment-resistant depression. The most difficult cases come through her door, and Susa is always ready to discuss treatment options, medication, and symptom management but draws the line at engaging with feelings. A strict adherence to protocol keeps her from falling apart. But her past is made present by one patient, Jim, whose struggles tear open Susa's hastily stitched up wounds, revealing her latent feeling that she could have helped the people closest to her, especially her adored, cool, talented graffiti-artist brother.
