Good book on witchcraft" is an oxymoron. Your curses will alight on you.
I think I'll stay away from giving you any advice. You should try to resolve your problems without resorting to casting spells. I find life is a lot easier that way, because the Gods help those that help themselves.
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.
