Deadly Intent by Christy Barritt

Sarah Chamberlain enjoys a new life far away from her abusive ex-husband, thanks to help from Vanishing Ranch. But when she starts to have unexplained, dangerous episodes and suffer memory lapses, she begins to doubt her reality.
She senses her ex has found her. But she doesn’t know if the problem is real or if her mind is playing tricks on her. She can’t contact the police—they would ask too many questions. So, she turns to the very people she knows can help her.
When former Secret Service agent and Vanishing Ranch operative Ruger Stark is assigned to check in on Sarah, he comes determined to find what exactly has her so spooked. But when he arrives at her lakefront home, he realizes he has much more to handle than a typical protection detail.
Ruger and Sarah must stick together to sort through the lies and uncover the truth. Is Sarah drowning in confusion. Or is someone playing a deadly game?
