I have only finished Interview with the Vampire and Memnoch the Devil.
I am in the process of reading The Vampire Lestat. (I'm up to Armand's part of the book ♥)
I own and have not read Queen of the Damned yet.
The rest, I have yet to buy. (it took me two or three months to get Interview, Lestat and Queen. I ended up buying a three-in-one book... And I ended up having a copy of Lestat and Queen in a pile of books *which I dug through looking for them...)
