Truck's Temptation. Ranger Regiment MC, #8

A rich man wants her destroyed. She's spent three years learning to stand alone. Sierra Mathis clawed her way out of addiction with nothing but willpower and rescue horses. Three years sober, she's rebuilt everything-her career, her reputation, her fragile stability. When a wealthy horse breeder's stallion dies at her facility, he decides she's the perfect scapegoat. His lawyers send threats. His men burn her barn.
And Sierra discovers that standing alone might get her killed. Then a quiet biker with steady hands offers help she never asked for. He spent a decade calling fire from the sky. Now he's found something worth protecting. Derek "Truck" Jackson was an Air Force Combat Controller embedded with Rangers, the voice that brought hell when his teams needed it. When friendly fire killed two men on his coordinates, he stopped trusting himself with anyone's life.
Being steady, reliable, precise-that's all he has left. Then a fierce woman with glass in her hair walks into his world, and every protective instinct roars back to life. She's being hunted. And Truck discovers that being steady isn't enough when someone finally makes him want to fight. The patriarch has money and hired killers. Truck has brothers and rage. Preston Whitmore built his empire crushing people who couldn't fight back.
The vet tech with her damning evidence is just another problem to eliminate. He doesn't expect combat veterans who answer threats with devastating precision. When Whitmore's mercenaries assault the MC compound, the Rangers respond with overwhelming violence. And Truck discovers that protecting Sierra isn't club business anymore. It's personal. It's primal. It's the first thing that's made him feel alive in years.
