His hand slides up my thigh, his mouth crashes against mine, and before I can stop it, I’m moaning his name as he spreads me open like he’s already claimed me. Because maybe he has… Knox Sterling isn’t just my ex-boyfriend’s older brother. He’s the brooding billionaire who broke away from the family business—and the one I’ve spent the past two years pretending not to notice. Quiet. Intense. Untouchable. Built like sin in a tailored suit, with ice-blue eyes that strip me bare every time he looks at me. After I’m left with a broken heart, I bury myself in my work. But a twist of fate pulls me straight into Knox’s orbit. Now I’m designing his newest Manhattan real estate project, and all the late nights, close proximity, and simmering tension finally explode into something we can’t undo. What starts as a single, impulsive night turns into a secret neither of us can stop chasing. It’s addictive. It’s reckless. And it’s so far past the line I can’t even see the rules anymore. But when my ex tries to come back into my life—apologizing, promising everything he never gave before—everything spirals. Now I’m trapped between two rival brothers: the one who betrayed me, and the one who ruined me for anyone else. I know this won’t end well. But I can’t bring myself to walk away.
