Crossing the Line by Laura Farr

Ten years after surviving something no child should ever endure, Hallie Anderson is ready to stop hiding in the shadows. With a job she loves, friends who care about her, and a fresh start in an new apartment, she can finally put the horrors of the past behind her.
Or so she thinks…
When the past merges with the present, Hallie once again feels like a scared and vulnerable thirteen-year-old. Desperate to keep her new life, she’s reluctant to accept help, but when events take a dramatic turn, she realizes if she wants to stay alive she has no choice.
What she doesn’t expect is for the help to come from Sawyer Mitchell, a Close Protection Officer who looks like he should star in Hollywood movies rather than watch her every move.
For Sawyer, protecting Hallie will be like every other assignment. He’ll do what he needs to be done then walk away. He never gets close to a client. It makes protecting them harder, but all that changes when he meets Hallie. He’s drawn to her, instantly aware she isn’t like anyone else he’s protected.
Can Sawyer protect Hallie and keep his feelings under control, or will he cross the line and put them both in danger?
