Kill Switch by Penelope Douglas

It was fun, though. And I was too distracted to be worried
about the shitstorm at my house.
“Oh, shit!” Isabella shouted.
“What?” Jade asked.
“There! When the light flashes again, look.”
I gripped Isa with both hands, huddling behind her and
waiting for whatever was coming.
“Oh, shit!” Jade yelled.
What? What was going on?
They laughed. “He’s getting closer every time the light
flashes!” Jade squealed.
And then I heard it.
The fucking chainsaw.
I groaned, my knees shaking. I hated Leatherface.
Laughter and shrieks, and then we all stumbled as several
chainsaws raced in, chomping at our legs with their harmless,
chainless saws. I hopped from one leg to the next, trying to
keep hold of Isabella as we all struggled to tear away from our
attackers. She grappled for my hand, but all of a sudden, the
wall behind me gave way, I fell through, losing my grip on her
arm, and freefell backward onto the hard cement before I
heard a door close, and all the screams and chainsaws faded
away.
I was suddenly in silence.
I pushed off the cold floor, held out my hands, and walked
back in the direction from where I fell. What the hell?
At least, I thought it was the direction. I might’ve gotten
spun around as I fell into the room.
“Isabella!” I called out, my hands landing on a wooden
wall. I patted around for a door knob or hinges—anything to
tell me where I was at or how to get out.
“Jade!” I bellowed.
