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.
