Flatline's Fortitude. Black Hills Riders MC, #15

She refused to sell. Now a billionaire collector wants to take everything she has. Tess Brogan inherited two things from the uncle who raised her: a garage on the outskirts of Sturgis and the stubborn refusal to break. When she pulled a 1969 Charger R/T from a barn auction-one of five hundred ever made-she thought she'd found the project of a lifetime. But Warren Ashby has wanted that car for fifteen years, and the woman who told him no is about to discover what happens when a man with unlimited resources decides to take what he can't buy.
He saves lives with steady hands and ends threats with the same ones. Ryan "Flatline" Caldwell earned his road name when his heart stopped twice on an operating table in Iraq. Now the Black Hills Riders' combat medic carries a trauma kit everywhere he goes, because the one time he didn't, a brother died in his arms. When he rides into a Sturgis garage for a tune-up and finds a woman under siege, he doesn't walk away.
She's fierce, she's fighting, and she's about to become his. Too bad the billionaire has no idea what he just started. What begins as protection becomes possession. But Ashby has an eight-man security team, a lawyer who buries people in paperwork, and a specialist who burns what he can't steal. Tess's shop. Her legacy. Her freedom. Everything is leverage for a collector who's never been told no twice.
In the Black Hills, the club handles problems with violence, not negotiation. And Flatline is about to show a billionaire what happens when you threaten what belongs to him.
