Introduction (A/N)

Percy Jackson has broken up with Annabeth Chase, who he has been dating for 11 years. Life has been good to him for the time, and he wishes it stays forever.
But the Fates have other plan.
Being told that he was a reincarnation? That wasn't surprising. But being thrown back to the world where he came from? Oh Hade-

Note : I don't own the franchise for Harry Potter or Percy Jackson, they belong to JK Rowling and Rick Riordan respectively.
