You should come back to that book after you haven't read it for a while, do it for leisure, and see how you feel.
That book is a classic, and should be enjoyed by everyone
The problem with high school english is that they force you to read "classic literature", analyze the shit out of it, and then expect you to like it. I loathed The Scarlet Letter. Not only was it the most boring piece of lit i've ever read, but writing essays on it over and over again just killed any chance I might reread it in the future
There really needs to be more Vonnegut in high school
