Don't Make A Sound (Laughing Jack X Reader)

After witnessing the horrible murders of your parents at the age of 7, you haven't been the same since. You become a mute, shutting yourself out from the world, not doing much. The only company you have are the voices in your head and books. Reading became one thing you loved to do, as well as music.
When you finally turn (your age), your adoptive parents try to cheer you up by taking you to the library. Once you get there, you feel a pair of eyes on you.
After a week of being paranoid of everyone and everything, your foster parents go on a business trip. You know that whoever is after you, will attack soon. Will you survive the attack? Who has been watching you and what do they want with you?
