Harry Potter|Trapped In the pages

I think I broke the story forever

It all started with me being in the classroom.It was the romanian lesson,wich was boring soo maybe what happend was better than being bored. I picked up my book from my school bag and opened it. As usual I had my boring books (whatever)and my book.Harry Potter and the half blood Prince. I open my book at the page of the book sign was. And "Boom". Suddenly I got teleported in the book.Dumbledore open the door. He was right in front of me.He asked a woman who was near his back:
"Is he the boy?"he asked the blonde woman
"No,the one in the back"she replied.
I got shocked,is this that scene?it couldn't be! But for my concern when I turned my back...Tom Riddle(Voldemort whatever) was there,the boy who is going to be the most powerfull dark wizards of all the times.He was staring at the floor careless.
I jumped at him and knocked him uncouncis,Dumbledore came at me, and grabed my hands:
"Stop you buly,you've done enough bad to this child!And he gave me a discusted push back.
"Dumbledore,I come from future you need to kill this child !I said loudly
"How do you...?"
"Know your name?"I said like it was a frequently asked question.
"Yes?"
"Long story, I know you really know you can ask me whatever you want to to see that I'm not telling you lies!"
"What wand do i have?"
"You posses the elder wand,sir,I know that you feel extremly guilty for your sister and that you wanted to be a pure blood suprematist and a lot more.God!You have to belive me!
I think he got a central brain freeze. So I took his wand from his hand, he haven't did anything to stop me.
I don't to Tom and said: Avada Kedavra! SUDDENLY(...)
