Crossing the Line by Laura Farr

Ten years after surviving something no child should ever have to endure, Hallie Anderson is finally ready to stop hiding in the shadows. She has a job she loves, friends who care about her, and a fresh start in an apartment of her own. She can finally put the horrors of the past behind her. Or so she thinks.
When the past merges with the present, Hallie is soon feeling like the scared and vulnerable thirteen-year-old of ten years ago. Wanting desperately to hold onto her new life, she’s reluctant to accept any offer of help. As events take a dramatic turn, she quickly realizes if she wants to stay alive she has no choice. What she doesn’t expect is the help to come in the form of Sawyer Mitchell, a Close Protection Officer who looks like he should be starring in a Hollywood movie rather than watching her every move.
For Sawyer, the assignment to protect Hallie is like any other assignment he’s taken on. He’ll do what he needs to do and then walk away. He never gets close to a client, it makes protecting them all the harder if he does. All that changes when he meets Hallie. He’s inexplicably drawn to her, knowing instantly she isn’t like anyone else he’s protected.
Can Sawyer protect Hallie and keep his feelings for her under control, or will he cross a line, putting both of them in danger?
