Blood & Throttle by Nova Kane

The streets run red with blood in The Gauntlet—a brutal underground death race where the fastest and the deadliest battle for power, money, and survival. There are no rules. No second chances. And the only way out is to win… or die.
When Sienna “Sin” Vega is forced onto the starting grid, she knows she’s being set up to fail. Framed for a crime she didn’t commit, she’s given one shot at freedom: race. Survive. Kill if she has to. But the men in The Gauntlet don’t take kindly to a woman on the track—especially one who refuses to submit. Beaten, hunted, and marked for death, her only hope is to trust the devil on a bike.
Enter Riot Carter, a legend in the underground circuit. Unbeatable. Ruthless. He’s got the fastest bike, the deadliest reputation, and a past soaked in blood. He doesn’t trust anyone, and he sure as hell doesn’t save people. But when he sees Sienna fighting to survive, something in him snaps. She’s not just another racer. She’s something else—something dangerous. Something he’d kill for.
Forced into an uneasy alliance, Riot and Sienna tear through the city’s crime-infested underworld, leaving a trail of bodies in their wake. But The Gauntlet isn’t just a race—it’s a bloodsport controlled by powerful men who play god. The deeper they go, the more they realize the real game isn’t about winning. It’s about who gets to live long enough to cross the finish line.
And when the world comes for his girl, Riot’s ready to remind them all why they should have left her the fuck alone.
