(Launguage warrning, there will be cursing in this story)

Percy Jackson a boy that has been through so much as a demigod but what the demigods don't know is that Percy was fighting monsters before they even knew him. Percy's mom is a hunter and Percy and Sally have been hunting for a while, and what if they have some ties to some Winchesters.
