In the wake of personal loss, Philadelphia narcotics detective Doyle Carrick loses his temper—and gains a twenty-day suspension for unprofessional behavior. Now he’s laying low at a house he inherited in rural Pennsylvania. But Doyle quickly discovers that Dunston, PA, has plenty to keep him occupied.

When a drug bust goes bad and the threats against Nola turn violent, Doyle begins to realize that what’s growing in the farmland around Philadelphia is much deadlier than anything he could have imagined . . .
