Bodies pile up across Chicago as a new opioid called Edge claims victims. A college student dies. A new mother overdoses. Three poker players never make it home. Detective Harriet Foster knows five deaths mean more will follow. Her team searches the city but finds nothing. No dealers, no suppliers, no answers. Then Edge strikes inside the police department itself. Someone close to Homicide becomes the next casualty. Foster refuses to let this case slip away like others before it. Her last investigation left her reputation damaged and her career hanging by threads. Colleagues whisper about her methods. Supervisors question her judgment. Now she stands at her own breaking point. The drug threatens the city while her personal demons threaten everything she has left. Foster must solve the case before Edge kills again. She also must confront the wreckage of her past choices. Both battles will test her limits. Victory in one might cost her the other.
