I know, I know, I'm a sucker for punishment. His books are not easy to read, meandering, long winded, and often times deliberately confusing.
This time he even put in some self mockery - one of the characters asks the writer "Who are you explaining all this to?" Listen mate, I'm here for your bizarre mind full of rural folklore and rituals, not for the detailed explanations.
But still you suffer through the whole thing because man he has a damn twisted mind, and he enjoys unsolvable locked room mysteries. A lady shaman who offers herself in self sacrificial sky burial? People who disappear from the island completely after being witness to the horror. A young girl who manages to poison 6 adult scientists / students.
Yeah, I still read through the entire book.
