I'd probably say Queen of the Damned just because I liked exploring Lestat's more human side. I suppose I've always been attracted to following how someone that seems like a monster had their beginnings. Good writers always give you the feeling that anyone if given a certain environment and circumstances could easily turn into a reviled villain.
The Tale of the Body Thief - The idea of God and Devil are on different terms than what the Church portrays and the history to include vampires and their existence in the world.
Vampire Lestat - none of that self-righteous stuff from Louis, all excess and ejoyable melodrama :).
I liked the Vampire Lestat but I also enjoyed Queen of the Damned. Interview with the Vampire will always have a special place for me it was my first vampire novel after that I was hooked! Ann Rice has a phenomenal talent of weaving you into the story with her imagery.
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.
