A deeper darkness

As a medical examiner, Samantha Owen's job is to make a certain sense of death with crisp methodology. But the day the Tennessee floods took her husband and children, the light vanished from her life. She's pulled into a suffocating grief until she receives a peculiar call from Washington D.C. On the end of the line is an old boyfriend's mother, asking Sam to do a second autopsy on her son. Eddie Donovan is officially the victim of a vicious carjacking, but the forensics tell a darker story.
