I'll give it a read this week sometime.
Two types of history that have been growing on me lately are alternate reality history. I used to not be a fan of it at all, but it can make you think about possibilities if certain events did not happen or happened in a different manner. I used to really frown on it, but I am seeing some value and it can be entertaining.
The other type is Memory History, I used to think that was a bit of a crock, but I read a book on Vichy France that was presented in that manner and I see value in that for certain topics ... and Vichy France is probably the poster child for this.
