|Great storyline, and very captivating throughout. I would like to get to know Mark a little better so that I can feel compassion for him. Why is he typing in a dark room? Did he lose his job, and is now trying to conserve electricity? Or is he hiding from the enemy, who caught him spying on them while they ran tests for human androids?
Other then Marks dark hair and blue eyes there's not much else about him. Is he fit, does he work out, is he a nerd or a ladies man.
Also, the knocking, is it intense enough to vibrate the floors and walls, does the knocking become so intense that it rattles Mark's ears and his brain.
This story has the potential to become a screenplay. Keep on, keeping on.
