I’ve loved Sienna Carter since the moment she walked into my best friend’s bar looking for a job. She’s everything I’ve always wanted in a woman—brave, beautiful, and a damn good mom to her son, Colt, who feels like the kid I never thought I’d have. But Sienna is also 15 years younger, and I’m an outlaw biker with a past soaked in blood and prison time.
So I’ve kept my distance. Vowed to protect her from afar. Made sure she and Colt were safe without crossing the line I set for myself. Until she started tearing down the walls I built around us.
Then, when her past catches up and threatens to take her and Colt away, I realize I can't stand to lose the family I never thought I deserved.
Now I’ll stop at nothing to save what’s mine.

If there’s ever been a cautionary tale about falling from grace, I’m it. Raised in an ultra-religious family, I was supposed to be the perfect daughter. But one frat party during my sophomore year at Oklahoma State changed everything. I woke up sore and foggy… and two months later, found out I was pregnant. I couldn’t even remember losing my virginity.
When I told my parents, they didn’t care about the circumstances. To them, I was a disgrace. They kicked me out, and I spent years working dead-end jobs, trying to give my son, Colt, a stable life.
Now, we’ve finally found a home in Broken Bend, South Dakota—and with it, something I never a family. The Tempest Knights MC took me in, but no one’s looked out for me like the club VP, Diesel. He’s been there from the beginning, watching over us, loving Colt like his own. And I know he feels something for me, even if he refuses to admit it.
But I’m done waiting.
I’ve finally found a place where I belong, and I won’t let fear—or my past—steal it away. Can I convince the broken biker I love that he deserves happiness, too? Or will the demons from my past tear it all apart before we even have a chance?
The Tempest Knights MC is packed with morally gray heroes who’ll do whatever it takes to protect the women they love. If you crave fast-paced, insta-love romance with a touch of suspense and a HEA—jump on, hang tight, and enjoy the ride .
