She's determined to find her father's killer...
FBI Agent, Toni Long, lost her father a year ago when he was killed in a joint FBI and ICE investigation led by Clay Byrd, a man Toni had found herself infatuated with. Unfortunately, the killer escaped, and if Toni hadn't been distracted by her attraction to Clay, maybe her father wouldn't have died. When she receives an anonymous tip on the killer's identity, she follows the lead and an attempt is made on her life. Clay, having received the same tip, comes to her rescue. Thinking he can help find her father's killer and keep an eye on her safety too, he quickly offers Nighthawk Security's help.

But she first has to face down her own dark past.
She fights the idea at first, but she will stop at nothing to find her father's killer, even if it means partnering with a guy she has feelings for. But as the investigation unfolds, they unearth deep, dark family's secrets that are more dangerous than anything Toni could imagine. Problem is, Clay is right there by her side, offering her comfort and support, and protecting her from menacing danger. She soon has to fight feelings she's developing for him when her focus should be on the investigation and staying alive.
