Thirty years after losing a parent to a hit-and-run drunk driver, FBI agent Alex Troutt finally confronts the killer - the same man who just murdered the Boston police chief. And what Alex pulls from him shatters her core. Armed with little more than hope and a shred of decades-old evidence, Alex chases a memory from her past, hoping that she'll find the mother she never really had. With her old buddy Archie on board - as much as ever can be - the hunt takes her deep into the foothills of West Virginia. A fanatical religious cult has created its own society. Clinging to a whisper of hope, Alex must out-think and out-duel everyone in her path to right a 30-year wrong. Will Alex's quest to find the truth destroy her life all over again?
