Natchez Trace Park Rangers 

After being forced to kill an FBI agent gone rogue in self-defense while working in the violent crimes unit for the Investigative Services Branch, ranger Madison Thorn is comfortable with her move to the fraud and cyber division. At least numbers don't lie. So she's less than thrilled when a white-collar crime investigation in Natchez, Mississippi, turns violent. She could also do without being forced to work with former-childhood-enemy-turned-infuriatingly-handsome park ranger Clayton Bradshaw.
When a woman who looks just like Madison is attacked on the same night Madison's grandfather is shot, it becomes clear that there is something much bigger going on here and that Madison herself is in danger. Madison and Clayton will have to work together--and suppress their growing feelings for one another--if they are to discover the truth before it's too late.
