After his daughter overdosed and died, William Thomas Knox brutally murdered billionaire Skip Buchanan, patriarch of the family many hold responsible for the American opioid epidemic. Online communities glorified Skip's death - one murder to balance out the loss of one million innocent people - and turned Knox into a hero.

One year later, veteran Harper Scott is out of work and just desperate enough to take a job protecting members of the hated Buchanan family. Then, as the online mob grows and death threats against the Buchanans reach a fevered pitch, another Buchanan is murdered and Harper is thrown into a race to find the killer.

There are precious few Americans who have not been harmed by the opiod crisis. But how do you find a killer when there are millions of suspects?
