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.
I will not say about novels because I liked most of them and would have read them even if they were not in the curriculum. But regarding poetry, school definitely made me hate it Instead of introducing me smoothly to some of the greatest poets, what it did is taking a poem of 10 lines and stretching it to a month of analysis of each syllable of the said poem. I had to reach 30 to open a poetry book again, and thankfully this time I appreciated it fully.
