Kill Switch by Penelope Douglas

I inched to the right side of the hall, the locker doors
clanking against their frames as I moved from one to the other.
Even if it was a real fire, firefighters would be here soon. I
couldn’t be completely alone.
“Hello?” I demanded. “Hello! Anybody there? I need
help!”
I followed the path of the lockers, trailing down the right
side of the hallway. When I came to the end, I rounded the
corner and pawed the wall until another row of lockers began.
Okay, okay, okay… If I followed this, and kept going
straight, it should lead me to the doors leading to the front of
the school.
“Hello?” I called again.
My hands shook.
I should’ve told Rika to come back for me. Why was I so
stubborn? Even if she was forced to exit the building by the
teachers, she would’ve known to tell them that I was in the
library waiting for her, and they would’ve sent someone to get
me.
“Hello?”
Then, all of a sudden, there was a pounding on the lockers
ahead.
I paused for a split-second, listening.
“Hey,” I said to whoever was down there. “Can you help
me? Is everyone outside? Can you help me get out?”
But there was no answer.
The sound happened again. Bang, bang, bang… on the
lockers, and I narrowed my eyes, confused.
“Can you help me?” I shot out, trailing down the lockers
faster. “Please, can you…”
My hands landed on a tall body with a broad chest in a
collared shirt, and I jerked back.
