Shadows in the Night — Linda Turner

Los Chisos. They were ruthless outlaws who smuggled desperate Mexicans into Texas for an outrageous fee, and they would have no qualms about killing border patrol agent Samantha Spencer. Then one of them, the mysterious arid Handsome Ross de la Garza, claimed her as his own. For some reason he was protecting her.

Ross had never met a woman who needed his protection less. Fragile? Hell, no! She was bold, brassy and as strong as a horse. Yet Ross knew from the beginning he'd risk his cover for her. She was his. And if they ever got out of this mess alive, he'd prove it!
