Sinful Beauty - Arrow Tactical Security, #6

When he lures the girl, it's just another day undercover until the unthinkable occurs. She steals his heart and disappears. To the world, billionaire Tristan Wagner is a playboy living a high life. In reality, he's an Interpol agent determined to stop corruption.  In an undercover op, he targets the woman he suspects is part of a twisted scheme within the company his great-grandfather founded. The investigation requires time, and the younger woman becomes his favorite pastime-until she disappears. Uncertain about who he can trust, he reaches out to his contacts in an elite black ops security firm based in the United States, the same firm he worked with on a connected abduction. Lucia isn't looking for love, especially with the coddled casanova.
After all, if he ever learned about her family, he'd want nothing to do with her. It's her hope their little fling will give her the push she needs to finally make changes in her life. That's the intent, until her life goal becomes staying alive. Fighting a race against time, Tristan rushes to rescue her and uncovers truths he never imagined, realities that alter his world and force him to face an impossible choice between his family's legacy and the remarkable woman he's grown to love.
