The Flash

(A/N This is an assessment I got for english. I'm not sure how good it is but I think its supposed to be pretty cool. Its about zombies. This is the Intro that the teacher gave us.)

It had been 260 days since the world ended in the Flash.
Even now, no one knew exactly what the Flash was, or why it had turned all electronic devices to slush. And no one knew why most of the adults who’d seen it had either died...or become something else. Petey said it was some kind of attack by aliens from outer space, but I wasn’t so sure about that. Petey thought everything was to do with aliens from outer space.
Someone sounded the alarm, a screeching blast of a trumpet that echoed through the underground bunker that was home for me and about a hundred other kids. Kira couldn’t actually play the trumpet, but she was excellent at making a noise. I rolled off my bed, grabbing for the crossbow that I always kept beside me and running for the trapdoor that led outside. Probably just a false alarm, we’d already had three this week.
But when I scrambled through the trapdoor and into the open air, I saw it – the telltale cloud in the distance, caused by thousands of clawed feet kicking up the dirt as they ran.
The Screamers were coming.
