The Knife

Gravity Falls fanfic! Dipper just wanted to unlock the mysteries of the town of Gravity Falls... But this time he's bitten off more than he can chew, and Mabel has gotten thrown into the mix too! Bill has tortured them for weeks, carving odd symbols into their skin. Even if they survive, will they ever find out the meaning of the scars they will bear? (This is my first fanfic so don't judge. Also Beware: FEELS ALERT.)
