" We can’t just go around resurrecting people, Johannes. It’s against nature.’
‘Says the vampire. Truly, Horst, nature lets all sorts of awful things through on the nod. What I propose doesn’t constitute awful in the pejorative sense to my mind.’
‘What gives us the right…?’
‘I’m a necromancer. I claim the right. "

― Jonathan L. Howard , The Brothers Cabal (Johannes Cabal, #4)
