The feeling was mutual—until it wasn't. A vacation meant for relaxation with her friend Rhoda takes a different turn when Joan finds herself tangled in a steamy, reckless encounter with the one man she swore she’d never want.

He is a 10 but he is a decade older than me, my brother’s best friend, a therapist who wants to counsel me and... he likes to hurt little girls like me. “What were you doing this morning?” “I was meditating.” He is right. I am a terrible liar. Aiden raised his eyebrows. “Is that so?” He waited for my answer, crossing his arms over his chest. I got distracted by the way his biceps bulged. He noticed me staring. I glanced down at my lap, twiddling my thumbs. “Y-yes, Doctor Aiden, I was meditating and I-I focused on my breath like you taught me—” “Why are you lying to me, Ivy?” My head snapped at him. “I-I am not lying.” Aiden tilted his head and my throat went dry when he said, “Then why did I hear your voice moaning my name when you orgasmed with your fingers inside you?" He is her first love. She is his best friend's little sister. Will a chance reunion lead to true love? I was a good girl. An honor student. A dutiful daughter, sister and a sweet girlfriend to my boyfriend until I found him in my best friend’s bed. I didn’t want goody-two-shoe nice boys who gave me empty promises. What I wanted was a man who wouldn’t hurt me. When I found my brother’s best friend, Aiden Stone, with only a towel around his hot Greek body dripping wet from a shower, I decided that what I wanted, what I had been wanting for years, was him. The only problem? He is a decade older than me, my brother’s best friend, a therapist who wants to counsel me and... he likes to hurt little girls like me.

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.

Elle Bennett and Cassie Reed have been inseparable since the day they were born. Bound by friendship, family, shared memories, and many rules - but there’s one rule that mattered more than all the others: your best friend’s brother is off-limits. For years, keeping that promise was easy - especially when Noah treated Elle like a little sister, and she, her big brother. During his final year and her 10th grade at Brookridge High School, something shifts, and what begins as quiet and confusing soon turns into something neither of them can deny. Breaking this one rule could cost Elle not just her first love, but the most important friendship she has ever known.

Zayne Bellandi was never supposed to matter. Not as my best friend’s brother, not even as my ex-boyfriend’s best friend. And definitely not like this. He’s dangerous, annoying, untouchable. The kind of man who ruins lives without even trying. But one night blurred every line I swore I’d never cross. Now he looks at me like I already belong to him, like walking away isn’t an option. And maybe it isn’t. Because the more I try to resist him… the more I realized I don’t want to.
