As the days pass and emotions run high, the careful distance between them starts to crumble. One unforgettable night and everything changes. Now the line has been crossed, and neither of them knows if their friendship or their family will ever be the same again.

I’m not here to make friends. I’m here to graduate top of my class, get into the best law firm, and make my brother proud. What I’m not here for? Sharing an apartment with Cade freaking West. My brother’s best friend. Tattooed, cocky, insufferable. A walking red flag on skates with a motorcycle named Roxie and a different girl in his bed every night. We don’t get along. We never have—especially not after what happened. He hates me for it. I don’t regret it. I was right. But the longer we’re forced to live under the same roof, the harder it gets to ignore the heat. The tension. The way he looks at me like he’s two seconds from ruining my entire life.

“My brother would kill you, Roman. Hell, I shouldn’t even be here!” He moves closer, blocking the exit. “He’s not here, and you’re not telling me to stop, Nikki. So, why don’t we stop lying to each other and admit the truth?" I glare at him. My heart’s slamming against my chest. “Which is what exactly?” A wicked smirk curves his lips. “That we want each other. Always have. No matter how badly we shouldn’t.” *** Ten years ago, I almost kissed the one guy I should’ve stayed away from, my brother’s best friend, Roman Hayes. But then he vanished from our lives and has somehow become the person my brother hates the most. I haven’t seen him in years. The last place I expect to find him is at a high-end gala where I’m meeting potential sponsors for my charity, dressed in a ridiculously expensive suit and reeking of sin—and somehow, he might be the answer to all my prayers. But there’s a catch: I’m not supposed to be anywhere near him, and the moment our eyes lock, I know I’ve made the biggest mistake of my entire life. He’s my brother’s ex-best friend, after all, and there’s a spark between us that’s never been extinguished, and a truth neither of us wants to admit. But some truths are darker than I could have possibly imagined, and some games are too wicked and wild to be entertained. This man might just destroy my life in ways I never saw coming… And the worst part? I’ll enjoy every second of it.

Moving in with your best friend’s brother is already a bad idea. Moving in with the one who hates you? Even worse. Kassidy had nowhere else to go, so she ended up living in the same house as Eli Deering, the man who blamed her for the worst thing that ever happened to his sister and never once pretended otherwise. Cold, distant, and completely unforgiving, Eli made it clear she didn’t belong there. She knew better than to want him. She had always known better. One reckless night at a party blurred every boundary between them, turning years of hatred and tension into something dangerous, messy, and intimate. They spent the night together. Eli is looking at her differently now and Kassidy is running out of reasons to pretend she doesn't notice and must decide if he is the one person she should stay away from or the one she was never meant to resist?

My best friend had one rule: stay away from my brother. But what he didn't know was that his brother kept me up all night. Wren Mercer had spent years being just Ross's best friend. Fine with holidays at the Calloway house, years of watching Dani, Ross's older brother, move through life like nothing could touch him, fine with the fact that he never once looked at her like she was worth the trouble. So she did what any sensible girl would do, she found someone else. Blake Hendrix was everything that made sense on paper. Charming, attentive, and most importantly, not Dani Calloway. She told herself it was moving on. She told herself it was working. What she didn't know was that Blake had his own reasons for getting close to her, ones that had everything to do with the brother she was trying so hard to forget. When Ross invites her to move into their off-campus apartment, she tells herself it's still fine. She has Blake. She has a plan. Dani barely registers her existence anyway. She can handle proximity. She's wrong. Because Dani does notice her. He always has. What starts as tension becomes stolen moments, a secret neither of them planned, and the slow terrifying realization that this is the most real thing either of them has felt in years. But Ross is right there. Blake is closer than she thinks. And secrets don't stay hidden forever. She fell first. He fell harder. And what breaks between them might not be fixable.
