Definitely read these:

– Queen of the Damned (but the movie is terrible and only loosely simialr to the book, don’t traumatize yourself with that!)

– Tale of the Body Thief – Lestat takes Doing the Thing to an extreme.

– the Vampire Armand – bc of reasons. 

– Memnoch the Devil – this one presents some really interesting stuff on religion, it’s almost like fanfic of the Bible; I’m not a religious person and I still got alot out of it. Plus it has alot of Feels. 

They do get exponentially more insane starting with #5 (someone coined the phrase “the Vampire Crackicles” for those) but that doesn’t mean they’re not worth a try. It’s still intriguing to know what happens/happened to the characters. I think you should keep going in order and see what you think!
