Meet Shelli, a synthetic investigator that hunts defective and often dangerous machines. In its years of service to Homeland Security, Shelli has never questioned its purpose, never doubted its mission, and never failed in its task. Until now. Partnered with young analyst Jake August, Shelli finds itself wading into deep political waters after a US senator is brutally murdered, presumably by a synthetic.
