Two Souls Hollow

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.
Her best protection came from an unlikely bodyguard 

When secrets leak from The Gates, the hunt is on for a mole. All evidence points to Anson Daughtry, who knows their security inside and out. Only coworker Ginny Coltrane can help clear his name, but she's caught in the middle of a turf war between militants in the Smoky Mountains. More at ease behind a computer than with a gun, Anson makes for an unlikely bodyguard. But hunkering down in the Tennessee foothills, turns out Ginny's not exactly the "need to be protected" type. Still, with someone stalking their every move, Anson isn't about to let her out of his sight. Or, if he gets his way, out of his arms.
