Beautiful and brilliant FBI Supervisory Agent Emmanuelle Blanchet, known as Emmie to friends and family, was embroiled in the most difficult and challenging case of her life. She and her dedicated team were rushing against time to find and stop a serial killer before he found his next victim. Making the task even more daunting, evidence was piling up suggesting that these murders were somehow related to a cold case that her father had been involved in, and solved, 30 years ago. When one of the victim’s mutilated body is found in the Shenandoah National Park, Emmie encounters National Park Ranger Chief Joel McNeil. The attraction was mutual and intense.  But could she risk getting involved in a romance during an investigation? With her focus being primarily on her career, personal relationships were always put on hold. Would she be able to resist her powerful feelings? As Joel and her team work closely with her against time to find the killer, it becomes clear that she herself may be a target. Will they be able to find the killer before it is too late? Or will it be, as Darwin suggested, the survival of the fittest?
