The dare seemed harmless enough at the time. "I bet you won't go to Jake's party with Kieran," her friend had challenged, a mischievous glint in her eye. Now she regrets ever accepting.

The bass from the speakers vibrates through the floor, matching the erratic rhythm of her heartbeat. She takes a deep breath, the air thick with the scent of alcohol and sweat. Eighty-six days. She's managed eighty-six days without hurting herself, but tonight feels like the hardest test yet.

Her hands tremble as she pushes through the crowd, muttering apologies to people she doesn't know. When she finally reaches the bathroom, she fumbles with the lock and collapses against the door, sliding to the floor. The cool tile against her back provides little relief from the panic rising inside her.

Meanwhile, Kieran scans the party, growing concerned when he can't find her anywhere. He knows about her struggles, having heard his best friend - her brother - talk about them late at night. With a determined frown, he starts searching each room, his worry intensifying with every empty space he checks.
