Isla Montjoy has it all, a new career in nursing and a police officer boyfriend she adores—until she stumbles across proof of her boyfriend's corruption. Determined to protect his secrets, he attacks her and leaves her for dead. But against all odds, she lives. On the run for two years, Isla's life is far from assured as her would-be murderer doggedly tracks her across the UK, intent on silencing her forever.

On a climbing trip in the Scottish Highlands, Ben Pressley-Coombes encounters Isla, a beautiful woman who promptly pepper sprays him without warning or reason. After that rough start, Ben hopes never to lay eyes on her again—but fate has other ideas. Forced into an uneasy association that transforms into a deep-seated romance, the pair soon faces a deadly threat: Isla's relentless pursuer has discovered her hiding place. If she is to survive, she and Ben must outmaneuver the dirty cop and his treacherous plot to snare her.
