After a young woman addicted to meth dies from a fall, her bellicose father blames the Red Boyz, a gang that has formed on the rez. The charismatic young leader of the gang asks Cork O'Connor to set up a meeting with the father, saying he promises justice - but when he and his wife are shot execution style, the father falls under suspicion, though the DEA thinks there's a drug angle. Cork senses the native and white communities of Tamarack county are headed toward a tide of violence and works first with the Sheriff and then with tribal authorities to find out who killed the gang leader. I thought this was the far the best in this series since Blood Hollow. The framing device of a historical battle between Dakota and Ojibwa warriors and the present day tensions is thought-provoking.
