Supernatural Fanfic Pt.1

A monster killed your parents, you only barely escaped. So when a family friend takes you in, and raises you to see what's really in the world, you naturally want to help hunt down and destroy other monsters with your new family. Bobby Singer doesn't like that you want to hunt and he isn't happy with the Winchester family for encouraging you. So when you get injured on a hunt, he forces you out of the life. But when John Winchester goes missing and Dean shows up a your door in the middle of the night, you get sucked right back in. Danger abounds as Sam joins you and Dean in a desperate search for John and the monster that killed Mary Winchester.
