I’m guessing most of the VC Andrews catalogue is banned if “Flowers in the Attic” is banned.
This book had just come out my senior year in high school. I attended a Catholic, all girl high school and I got in trouble for writing a book review for our school paper about it. In the words of the administration, “It wasn’t appropriate reading for young ladies.” Never mind that EVERYONE was either reading it, had read it, or was waiting to read it. So even in 1980, it was controversial. I bought the next book in the series and my mom threw it in the trash.
