Literally any book that you now dislike due to school. This also applies to other literature styles as well.
Mine is The Hunger Games. I had to read it las year in school and it drove me insane. We started doing the novel study in early February and didn’t finish until May. I finished the book in less than two weeks, so I was pretty much just reading personal books all through English class for close to two months.
It’s not even like we had to analyze it super intensely. It was projects like ‘Make a playlist for a character of your choice’ and we had vocabulary tests every week, that were a joke. It was multiple choice for words like quest and forage. I know that English wasn’t everyone’s first language but come on.
I didn’t even like the book that much in the first place, so all of this was just adding to the misery.
You read Hunger Games for SCHOOL? Wow, what a waste. Did your teacher assign Twilight afterwards? Ugh. I think my high school teacher did a good job of making some difficult reading (Beowulf, the Canterbury Tales etc) accessible and I liked the authors she introduced - Margaret Atwood, Toni Morrison, George Orwell etc. But reading Johnny Tremain in middle school totally sucked. And freshman English in college was awful - the books were fine, the prof was useless.
I so wished we got to do something more difficult, but I had classmates who didn’t understand Hunger Games at all so something more advanced would have been too much for them.
