Write me a dark story

I love a good dark story, & I love making lil books for friends. For this swap you will have one partner and you will write them one orginal short story. It can be scary or not, about any subject you wish. After you write the story you will make a lil book for your partner, about the size of an 8x10 paper folded in half. Make sure you make a cover and put your name on it. This is senders choice so no down rating because you don't like the story. I will give you a long time to do this so be creative.
