No time to think. We run from the mob of zombies, tear along the corridor, knowing we don't have much time.
As we pass an open door to a classroom, Linzer ducks inside. "I'm hiding!" she screams, slamming the door shut on the rest of us.
Meths starts to slow but Stagger Lee bellows at him, "Leave her!"
We press on. My heart's hammering. I'm finding it hard to breathe. I was never the fittest - too many helpings of fries and not enough exercise. I start to drift towards the rear of the group. We turn a corner, then another. I've lost track of where we are. The zombies are drawing closer. The mutants in hoodies must be with them because I hear an occasional whistle.
I'm rushing past a window when I catch a glimpse of open space. I stop and yell to the others, "We're next to a courtyard. I'm jumping."
"We don't know what's down there," Trev roars. "It could be full of zombies."
I grin ghoulishly. "Only one way to find out." I back up from the window, then hurl myself at the glass, covering my face with my arms. There's a good chance I'll slice open a vein or artery, but I'd rather bleed to death than be devoured by the living dead.
I smash through the window and whoop insanely, half-terrified, half-buzzing. My arms snap open and flap wildly. A brief glimpse of the ground coming fast towards me. Then I land in an untidy heap and roll awkwardly. The air's knocked out of me. Shards of glass nick my hands and knees. But I'm alive. I'm not badly injured. And the courtyard's empty.
"Come on!" I shout at the others.
