Looking for a novel, probably in the fantasy genre.
From the point of view of a girl, who was abducted by some crazy and cruel supreme being, whom she calls 'father'.
She, along with other kids, was raised by this god. Every kid was taught a different skillset. They lived in a village which had zombies for residents. She was some kind of librarian.
Among the other kids there was:
- a necromancer girl who could walk the afterlife, 'father' killed her a few times, then resurrected her.
- a guy who could talk to animals, but lost the ability to communicate with humans,
- some other guy who was a warrior? and who was punished by 'father' for some minor disobedience by burning him alive in a sarcophagus.
It seemed as if all the kids raised by father were suffering from CPSTD, but they could do nothing to resist him and his 'education'.
There was some kind of taking leopard-god, whom the girl tricks into walking into a trap to get rid of him.
At the beginning of the story, 'father' disappears, and the kids - now adults - assemble to find out what happened to father and discuss the succession.
These 'siblings' (the successors of 'father') are all supernatural beings with long lifespan, possibly immortals, due to his lessons.
The siblings all lived in different parts of the world and returned after hearing of father's disappearance.
There's an enemy they should defeat who is more cruel than 'father'.
No idea about the cover; I read it anywhere between 3-10 years ago. I did not finish it, so this is all I remember.
