I did not care for this. A couple intentionally gives birth to deformed children and only loves them according to how deformed they are. Those siblings are in love with each other.  The narrator is obsessed with stalking and sexualizing her own incest daughter.

And yet, everything was still flat. I felt nothing but boredom. Not even a little hint of disgust at the Lilly and Al for what they intentionally did, not at the incest or the cult practices. Arturo, actually, was the most interesting thing about this book, and it still didn't hold my attention.

I contemplated DNFing at 16% but decided to stick with it since I was listening to the audiobook, and that's the only thing saving this from being a DNF.
