Recommend some novels for inspiration, please

I'm going to run Crimson Gutter and Chicago by Night. I don't feel ready.

BTW, I was going to read Fevre Dream (a vampire novel by George R. R. Martin), but there might be a better choice somewhere.

I'm familiar with "The Inquisitor" by Jacek Piekara, "Dracula" by Bram Stocker, "Interview With The Vampire" by Anne Rice and the VTM - Night Road game
