On the hill - Chanmin

Book description: A student council retreat was supposed to be quiet-just a few days away from school, buried in snow high above the world. But on the first night, something-or someone-turns the silence into a crime scene. When a body is discovered and the only road down the hill is swallowed by a blizzard, leaving becomes impossible... and trust becomes dangerous.

As fear seeps into every glance and whispered conversation, Seungmin begins to notice the cracks-alibis that don't quite fit, smiles that linger too long, secrets no one wants uncovered. Because the killer isn't outside in the storm.

They're already inside.

Series:
Behind thin walls, on crowded buses, in quiet conversations-danger moves unseen. A neighbor who listens too closely. A student running from a past he can't escape. An assassin who knows too much.
Their stories seem separate. Their lives, unconnected.
But secrets have a way of finding each other.
And when they do, survival is the only thing that matters.
