Broken and humiliated by her husband of ten years leaving her unexpectedly, Sophia Meadows muddles through her daily routine-writing computer programs and rarely leaving the house. That is, until an old friend from university shows up on her door with an offer she can't refuse: a chance to get away and heal in the Scottish Highlands of Inverness by flat-sitting.

Yet once she arrives, she soon discovers the offer is not what she bargained for: A police surveillance team is watching her every move and a mysterious man is after the contents of a safe hidden in a wall. After a break-in at the apartment, her path collides with DI Marcus Armstrong, the man in charge of the apartment surveillance. Sophia is swept into an investigation of fraud involving her university friend and into a sudden attraction with the handsome DI who finds himself drawn to her even though she's a suspect in his case.

With evidence piling up against her and her friend and the attraction between her and Marcus growing stronger, Sophia is forced to confront her broken heart and find a way to clear her name. In a tangled web of secrets and clues, can she and the DI work through their attraction and learn to trust each other in time to stop a criminal and possibly save a life?
