Sentinels — Matt Manochio

These are no ordinary killers. They don't distinguish between good and evil. They just kill. South Carolina's a ruthless place after the Civil War. And when Sheriff's Deputy Noah Chandler finds seven Ku Klux Klansmen and two Northern soldiers massacred along a road, he cannot imagine who would murder these two diametrically opposed forces. When a surviving Klansman babbles about wraiths, and is later murdered inside a heavily guarded jail cell, Noah realizes something sinister stalks his town. He believes a freed slave who's trying to protect his farm from a merciless land baron can help unmask the killers. Soon Noah will have to personally confront the things good men must do to protect their loved ones from evil.
