If You Know Her is a novel written by Shiloh Walker. It was first published in 2012.
Nia Hollister doesn't scare easily. She's returned to Ash, Kentucky, with a vengeance - and with a mission: find the killer who brutally ended her cousin's life. What she didn't count on was trembling with desire every time she sees Law Reilly. If any man can help her escape the nightmares for a while, it's him. But can she allow herself to take comfort in those strong arms when her cousin's killer still roams free?
She may think she's a bad ass, but she should not have come back to his town. He is watching her - as she slips into Law Reilly's house, as she storms into the sheriff's office. These men won't be able to protect her when her time comes. Timing is everything, though he can't wait forever. She's nosing around the woods, looking for his hiding place. Yes, he's watching her...through the window...in her bed.... If she's not scared, she should be...because he is very good at what he does.
