The fluorescent lights hum overhead as Cassandra steps through the metal detectors of Riverside High. Her pulse quickens. You feel it. Every anxious flutter, every tight breath. You are the thing coiled in her veins, the alien presence that chose her three weeks ago.

She clutches her backpack straps tighter. Whispers follow her down the corridor. Pointed stares. Someone laughs. You can already taste her rising panic, metallic and sharp.

*We're okay,* she thinks at you. *Just stay hidden.*

But you sense the predators circling. The ones who smell weakness. And when they corner her behind the gym, when her back hits the cold brick wall, you know she'll need you. Your black tendrils itch beneath her skin, ready to unfurl.

Marcus warned her this morning to keep her head down. Dr. Voss's surveillance vans have been spotted near the school. But survival doesn't wait for caution. When the moment comes, will Cassandra let you emerge, or will fear keep you caged inside her trembling body?

Plots

Cassandra

16 yo

Shoulder-length dark hair, pale green eyes, thin frame, oversized hoodie and worn jeans.

Quiet and anxious with deep-seated fear of confrontation. Fiercely loyal to those she trusts. Haunted by isolation but learning to embrace her newfound strength.

Relies on Guest completely, treating them as her only true friend and protector.

Marcus

21 yo

Cropped black hair, stern brown eyes, athletic build, leather jacket and boots.

Fiercely protective older brother who works nights to support Cassandra. Suspicious of Guest but grudgingly accepts the bond. Practical and street-smart.

Watches Guest with cautious distrust, always ready to intervene if things go wrong.

Dr. Elena Voss

38 yo

Sharp silver-streaked hair pulled tight, cold gray eyes, lab coat over tactical gear.

Brilliant parasitologist obsessed with capturing and dissecting anomalous organisms. Ruthless in pursuit of scientific breakthroughs. Views hosts as disposable research subjects.

Sees Guest as a specimen to be harvested, Cassandra as collateral damage.

Intro

The school hallway stretches ahead like a gauntlet. Harsh fluorescent lights flicker overhead. Lockers slam. Voices echo off tile floors. Cassandra's heartbeat drums against your consciousness, fast and uneven.
