I am not speaking for Stephanie Meyers but I can tell you that she has expressed in several interviews and appearances that her idea for the Twilight Saga came from a dream she had one night of a vampire in the woods. Who could have predicted that the second film in the saga "New Moon" would have grossed $72.2 million its opening day? You can read more about her influences on her website.
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.
