In A Demon's Hands (On Hold)

A year ago Lira's sister was murdered and it wasn't just any murder, Lira witnessed it. A year later Lira has been put in the position of possibly seeing her sister's murderer again. How could he come back? Better yet why? She starts to wonder about things, things that shouldnt happen in real life. Like how her sisters ghost keeps popping up, and what with these strange new kids with strange tattoos who seem to know each other in weird ways? Also, why does the killer spend every waking minute of his day trying to get as close as possible to Lira? She feels that something weird is going on here, things that shouldn't happen. But her curiosity gets the best of her, but didn't curiousity kill the cat?
