Writing In The Attic Rockwell, Any Books Like Flowers In The Attic?

Any books like Flowers in the Attic? - writing in the attic rockwell,

I looked at this question and some answers were given, but not what I want. Looking twisted novels (especially people who shoudn't together), tabboos stories and writing obscene like flowers in the attic.

I do not like The Ghost Writer, Ann Rice, or Jackie Collins. So please do not tell me to test them. Thank you!
