"Two members of a ruthless biker gang called the Sons of the Void show up dead at a cabin in the woods, and Wolf and his team learn violence in a neighboring county has bled south into their jurisdiction. Despite the easily explainable crime, the brand new sheriff in office is hard-pressed to look active on the case and sends his ringer -- Wolf -- to northern Colorado to help investigate. Unwanted and unwelcome by the locals, Wolf finds he's plunged into a territory where fear and silence reign supreme, and as he unearths more details about the crime, learns there's much more going on than meets the eye. More danger awaits, and not just for the criminals. Innocent lives are at stake, and the only man standing between them and certain doom is David Wolf." -- Amazon.com.
