Project Halberd: Vigilante by D.E. Sherman

Dana Morris lost her parents to a gun fight between two rival drug gangs three years ago. Since the cops failed to do anything about it, she’s decided to take matters into her own hands. Armed with a black market exosuit she refurbished, she turns herself into a vigilante. Her initial assaults on City Seven’s underworld drug trade go well, but when a powerful senator connected to the drug cartels steps in to take care of her, Dana finds herself unknowingly caught up in a fight that will break the rest of her family, one way or another.
