Wicked Fascination by J. M. Brister

Freya Morgan survives a terrible rape where she is scarred both internally and externally. The perpetrator is not caught, and while she tries to heal under the watchful eye of her father, the rapist continues to torment her through harassing phone calls. No matter where she hides, he somehow finds her. Fearing for his daughter’s life, Joe Morgan—the head of a major publishing company—decides to hide her away at one of his top author’s (and friend’s) summer mountain home. It’s a place so off the grid that there’s no way she’ll be found.

While Freya stays at Brian Ash’s guesthouse, she attempts to isolate herself, but Brian’s their attraction to one another keeps pulling them together. But he doesn’t know what has happened to her, and she’s terrified that he’ll find out. Meanwhile, her rapist is still on the loose and close on her tail.
