You cannot. EF doesn't support mapping table more than once and many-to-many relationship is represented by table mapping. Because of that you cannot use the table in two different many-to-many relationships (even they are actually the same but EF doesn't know about it).
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.
