After receiving feedback that this story started waaaay too slow. I have revised. I also cut it from 7k to 3k so that it would qualify for a contest. Here are my new first thirteen. I am looking for someone interested in doing a swap, and critique on the first 13, of course. It's a horror story btw.
Katherine watched from the kitchen window, in horror, as a shadow separated from the dark forest surrounding her house and lunged for the teenage girls that walked from Katherine’s driveway to her front porch. The shadow loomed over them like a skyscraper made from night. Katherine ran for the door, hoping the shadow hadn’t snatched the girls into the darkness. She knew the shadows were alive. She had heard their voices—whispers calling to her—she had thought, but they had used a name she couldn’t decipher.
She pulled the door open, darted over the threshold, and stepped around the girls to shield them from the darkness. Katherine whipped her head around, looking for the evil, but saw nothing.
“Uh…trick or treat?” one of the girls said.
Katherine jumped, spun around and looked at the girl who had spoken. Was this some kind of joke?
