Sanguina Cruenta
Konstantinos is one of those authors I argued with aloud while I read it. There is nothing of substance in his nocturnal witchcraft, and one of his other books appears to be exploiting lovecraft. Like... If you read Cunningham's two standing stones books, there's some meat to it. There's no meat in Konstantinos. He just skims stuff off everyone else's work, puts a patina off darque on it to exploit the gothy kids, and sells it off.
His writing voice always seemed very arrogant to me. And he screws around with the deities in his deities section. His whole attitude towards gods was very arrogant, actually.
What I'd recommend depends on what you're looking for. There's not much spirituality in konstantinos... But spirituality is a big area so I don't know what to recommend.
Yeah, he does have a very odd attitude towards gods. I did pick up on that. I also wondered if he was just trying to exploit the gothy types, considering the title and the way it was marketed. Still, I usually try to keep an open mind and give it a fair read. I totally understand your complaints about him. I'll give Cunningham a look.
