Time of Death

Sneaking out and drinking our way to my best friend's new hiding place, I meet a mysterious man who threatens to kill me, my dad, and my best friend, unless I choose one to kill. He deteriorates my somewhat normal life and creates a master plan to give me ultimatums. He wont leave me alone and he has other people like him come after me. Why is he doing this? What does he want with me? I don't want to be alone. He knows my biggest fears: lonesome and loss.
