The only example of this I have is when I read Anna Karenina (by choice) the summer after 8th grade. Took me freaking forever because it’s a giant book and I kept having to re-check it out from the library. The outcome at the end of the main character pissed me off so bad and I felt like I wasted all that time for the ending to just be what it was. I’ve never forgotten it and anytime anyone mentions that book I tell them that story lol.
