Disclaimer J.K. Rowling owns Harry Potter
When the clock strikes midnight on my heirs fifteenth year my heir will realize his true powers that have been kept from him since birth.
Salazar Slytherin 1002 AD
Harry was having a horrible summer so far. As soon as he saw Vernon at the platform he knew he would have a miserable summer. Right when he got to #4 Privet drive he was locked in the cupboard and only let out to do chores and go the bathroom twice a day. He was only fed once a day if he was lucky.
"I wish I could leave" thought Harry.
"10,9,8,7,6,5,4,3,2,1 happy birthday to me" Harry said
Or at least would have said because at that moment in a flash of white light Harry Potter was at #4 Privet Drive no more.
