What maketh a monster?
Imagine yourself waking up—six feet deep, dirt suffocating you—in an unmarked grave in the backyard of a vacant house after you had been missing for a year. Some psychopath is peering over you, calling you perfect, and you freak out and essentially suck the life out of him and take his memories, especially the ones of him killing a family. Thus, you learn you have a crazy new power that lets you sense killers in your midst. You don’t know how that has happened and why it happened, so what do you do?
