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.
Thankfully I almost never read what I had to for school, I just read what I wanted, but one author that I did read and hated every second of it is Marcel Proust. I feel like I would enjoy his books now, but I hated them so much when I had to read him in high school that I am hesitant to pick him up again. Forcing teenagers to read authors like Proust, Goethe and Tolstoy is a good way to put them off reading for life.
