Memoir. They sell well under that genre. Good luck :).
What do you feel inside. When you read it do you feel a tug of your heart or does it make sense to you when you look back. Or does it make you feel like you know a lot from looking back.
I may be young but sometimes the youth makes me smarter. Look back and read the book your book one more time. Then you will need to answer that for yourself.
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.
