It's been a while since I've worked with the Fluent NHibernate and am just currently getting back into the swing of it (wow there's been alot of changes since early 09!) and I think the answer to your question now is yes you can do this with the OverideAll functionality.
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.
