Sharp Edges {Jeff the Killer}

Kayla Riddle has heard legends of Jeff the Killer, the boy who went insane, murdered his family, and burnt down an entire city block.
She's been told that every night, he would go to some kid's house while they're sleeping and climb into their room, then wake them up and kill them.
What she wasn't told was that she was his next victim.
But is this demonic excuse for a boy more than he seems?
