Will the adventures of Harry Potter end with the 7th book Harry Potter and the Deathly Hallows?

Yes, very much likely. J.K. Rowling has said that if she even starts working on another Potter book, it won't be for another ten years or so.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
