There are two kinds of girls at Aurelius Academy. The ones who whisper Serayah's name like a warning. And the ones who wish they were her. Serayah has spent 19 years being looked at and never seen. Being present and never acknowledged. Learning early that if the world was going to talk about her anyway— she might as well give them something worth talking about. So she did. She became the chaos. The controversy. The girl your parents warned you about. She collected rumors like jewelry and wore every scandal like it was tailored for her. She was untouchable. She was fine. And then Aarav Kaelam happened. He didn't mean to. That's the worst part. When the college assigns him as her tutor, the last thing either of them wanted. Serayah brings her games and Aarav brings his walls. Serayah knows every kind of boy. The ones who want something from her. The ones who want to ruin her. But she has never met one who wanted absolutely nothing. She doesn't know what to do with that. But she's about to find out. His Ruin is the story of a controlled boy and a chaotic girl and the slow, inevitable, beautiful disaster of what happens when they collide.
