Status Updates From Geisterflut (Downside Ghost...

"...the remnants of what had once been a church, one of the many destroyed by furious citizens when Haunted Week finally ended. The country was littered with these brick and granite corpses, silent testaments to a system of belief that had served mankind for centuries but ultimately proved as worthless and obsolete as a black-and-white television.

Ok, wow, so this is actually the best UF re-read so far, the world & the magic system is so different, and ghosts instead of vampires, werewolves etc. Iirc she goes to the city (underground) in the 3rd book. Weird how I remember that & the ghost airplane (and a sorcerer later with a book), but nothing else. Will definitely read all the 5 books this time (and finish Zombie too afterwards).

"I do not need faith because I know the Truth. I do not need to believe. Belief is unnecessary when fact is Truth. I do not pray to a god. Prayer implies faith and gods do not exist. Only energy exists, and this is Truth. The Church shows me the Truth and protects me. If I hold to these Truths I will enter the City of Eternity, and there I will stay."
