Sierra
I keep my head down, my voice low, and my walls high.
I was the quiet one. The too-sensitive one. The girl who was always too much or not enough. I learned early to make myself small and disappear, but a dangerous boxer managed to see through my quiet.
He listens when no one else has. He doesn’t ask me to be louder, braver, or tougher than I am. And when my world starts to crumble, he’s the steady ground beneath my feet, holding me together with everything he has.
Falling for Connor means finding my voice, even when it terrifies me.
Connor
Sierra is everything I never had and everything I never imagined would be mine. She's soft, sweet, and so careful. A girl with anxious eyes and a heart too big for a world that’s been too cruel.
I watch her, I protect her, and I memorize every breath she takes. The world calls me “Killer,” the heavyweight champion who never loses control. But with Sierra, losing is impossible. She’s the only softness I’ll fight for, no matter the risk.
She thinks she’s invisible, but I see her. I feel her, and I’ll never let her go.
Undisputed Champion features Connor Graves and Sierra Willows. This possessive dark romance contains themes of obsessive behavior and morally gray characters who will do anything for those they consider theirs. HEA guaranteed!
