Shootout at Sanderson Stables

A couple years after Angela Sanderson's parents die in a tragic accident, her brothers start talking about selling off chunks of their property. Angie wants to revive the family business - it was all she had left of her parents, but though problems abound, the last thing she expected was to become hunted. After the first attack, her brothers were brought home from prison for their protection. Also to provide for their protection, four local cops became part of the crew, but neither she nor they realize how dangerous that masquerade could be.
