Hard Target

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.
She was trouble the size of Texas, but he'd cross every line to keep her safe 

Border patrol agent Reed Campbell knew when he found a blonde beauty hiding out in a crate of guns smuggled into Texas she'd be nothing but trouble. Emily Baker claims she was kidnapped, beaten and held hostage by Mexico's most elusive drug lord, a man Reed's desperate to bring down. But the sexy cowboy has been betrayed before, so trusting a stranger—no matter how strong their attraction—isn't easy. Still, determined to protect her, he takes her on the run, risking his life time after time. Suddenly, the man who doesn't do feelings is in big trouble. Keeping Emily alive is a problem. Keeping his hands to himself becomes nearly impossible.
