Private Investigator Kenna Devlin, still recovering from injuries sustained in her last case, agrees to track down the guy who "ghosted" her friend. He was a security guard at a pharmaceutical company, and he vanished without a trace. She quickly realizes he isn't the first person at Cantaldi Pharmaceuticals to die, nor will he be the last. When her lover, FBI Agent Paul Smith, disappears while investigating a cold case at the same company, she frantically digs into her own family history to figure out the connection. What she learns challenges everything she thought she knew about her life. Soon she has a bigger problem - keeping herself alive long enough to stop the killings. Past and present collide as Kenna and Paul struggle to stop those who would sell dangerous medical technology to the highest bidder.
