Before Sunrise

Ten strangers wake in a sealed underground room. No doors. No windows. No memory of how they got there. Then a screen comes on and a voice says: "Before sunrise, everyone in this room will die except one of you."They think it's a joke. Until the first person drops dead. No weapon. No struggle. Just gone. The rules appear: one of them is responsible for the deaths. Every hour, someone else will die.
The only way to stop it is to name the killer correctly before time runs out. Each person carries a secret. Each secret is connected. And one of them already knows how this ends. As the hours count down, ten strangers are forced to confess the worst things they have ever done the lies told, the evidence buried, the vulnerable people abandoned to protect themselves. What emerges is not just one killer, but an entire architecture of harm, built over years by ordinary people making ordinary compromises.
And the most devastating truth arrives too late:The killer was never hiding in the room. The killer was being created by it. A literary thriller about guilt, accountability, and what it costs to tell the truth when the clock is already running.
