  • It Ends with Us
  • The Hating Game

Perfect for you if...

  • You love the tension of forced proximity romance with genuine danger woven throughout, not just as a backdrop.
  • You're drawn to heroes with a tough exterior but real vulnerability underneath, especially when they doubt their own goodness.
  • You want steam and stakes without explicit scenes, and you enjoy series where each book deepens the world around a core security team.

Maybe not for you if...

  • You prefer slow-burn romances that take their time; this one accelerates when the threats escalate.
  • You're looking for a heroine who's fragile or needs rescuing in a traditional sense; Fiona is accomplished and independent.
  • You want literary complexity and moral ambiguity; this is a straightforward good-versus-bad-guy narrative.

About this book

Fiona Raven is a famous television personality known for her homestyle cooking with Italian influences. Her pre-packaged foods are widely sold, but she has begun receiving threatening notes. When her brother insists on hiring a bodyguard, Fiona learns it will be Ryder McClain—a man she has avoided because of her feelings for him. Ryder works for Black Tower Security and welcomes the chance to play a protective role rather than a villainous one. Fiona's brother, who is both his boss and best friend, warns him to maintain professional boundaries. Ryder believes Fiona deserves better than him, despite recognizing her as an ideal partner. As Ryder takes on the assignment, the threats escalate from notes to break-ins and corporate sabotage. He must uncover who is behind the danger to Fiona while managing his growing emotional attachment to her. Potential Threat is the first book in the Black Tower Security series.
