The Complete three-book series: Storm Justice, Storm Vengeance, and Storm Retribution.
Storm McKenzie stumbled into an opportunity to help deliver justice. In book one she is something of a voyeur as her partner does most of the "work." In book two she has a new partner and takes a more active role. In book three she confronts and partners with the person responsible for her internal rage. The rage that allows her to ignore the social contracts and morality that keep most of us from killing. Read all three to watch a vigilante's journey.
