The Vampire Lestat By Anne Rice.
I'm rereading this one out of pure love for it. It's one of the few books in the series where everyone makes an appearence at least once, if not repeatedly. Although I love Lestat unconditionally, I really love Marius the most; he's the most like me. He's really gorgeous, too.
Screw the Queen of the Damned movie- they fucked up all the characters and didn't even follow the storyline. And the most blasphemous thing of all is the guy playing my beloved Marius was some old and practically balding actor. I am appalled and discusted- Anne Rice was right to disowned that movie.
