Dr. Samantha Owens is starting over: new city, new man, new life. She's trying to put some distance between herself and the devastating loss of her husband and children -- but the old hurts leave scars. Before she has a chance to settle into her new position in Georgetown University's forensic pathology department, she's called to consult on three murders caused by an unknown pathogen in Metro Washington.
