It doesn't, hence the word "or" instead of "and." I was talking about three different features of the story, any one (or more) of which might appeal to someone.

Maybe I misunderstood your question, and you're asking how those three things exist in the same book? The story premise is very reminiscent of the popular creepypasta Candle Cove. I don't want to get spoilery, so I'll just say, as someone who was raised in a cult, you can have some genuinely lovely people who were fooled or were taken in as children.
