"I want you to take my virginity," I tell my best friend. He chokes on his drink. His eyes go wide, blinking at me like he misheard me. "Dawn." "Not now, obviously. Just promise me you won't let me turn twenty still a virgin," I say, biting my lower lip. He stares at me like I just sprouted two horns. His eyes move slowly across my face. His lips part. He says nothing. "Dawn," he whispers like a plea. For so long, I have loved him. I wanted all my firsts to be his. Instead, I end up in his brother's bed. Killian. I should stay away from him. I shouldn't want him. Not only is he cocky, arrogant — he's the bane of my existence. Yet when he touches me, it feels like I'm the most precious thing in his 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.

Synopsis: “Some mistakes ruin you. Others reveal who you really are.” Ava has always played it safe, witty, observant, and content staying in the shadow of her bold, magnetic best friend, Sophia.

Now, with secrets unraveling and emotions running raw, Ava must face the wrath of betrayal not just from Mason, but from Sophia too. Can love survive when trust is shattered? Or will the truth destroy them all? In a story filled with temptation, betrayal, and heart-stopping twists, Ava must decide: is forbidden love worth the scars it leaves behind?

Katherine Heart has been in love with Damon Rhodes for three years, which would not be a problem if Damon was not her ridiculously handsome best friend who keeps acting like her boyfriend without ever actually calling her his girlfriend. One minute he is kissing her breathless, telling her she is the only girl who truly understands him, and the next minute he is dodging every conversation about commitment with that stupid charming smile of his that should honestly be illegal. But when Damon drags Katherine to a luxury ring shop, she is convinced this is finally it. Until she realises it's not her. Humiliated, heartbroken, and determined to never let Damon see her cry again, Katherine throws herself into her internship at Rhodes Enterprises, where long hours and impossible workloads are easier to survive than watching the man she loves fall for someone else. There is only one problem. Nathaniel Rhodes, Damon’s older brother. Cold, terrifyingly powerful, and completely off-limits, Nathaniel is the kind of man who can silence an entire boardroom with one glance alone, yet for some reason, his icy eyes keep following Katherine everywhere she goes. And when one late night at the office leads Katherine to discover a side of Nathaniel nobody has ever seen before, his cock in his hands as he helplessly moans her name, her messy heartbreak suddenly turns into something far more dangerous. Now trapped between the boy who broke her heart and the man who could completely ruin her, Katherine is about to learn that love triangles are a lot messier when billionaires, jealousy, office scandals, and unresolved tension are involved. Because falling for one Rhode's brother was already a disaster. Falling for both of them? Absolutely catastrophic.
