I also read Lord of the Flies in school (probably 25/6 years ago), I think its one of those books they make everyone do. I think it was ruined for me just because I was gripped by it and reading a chapter a week then having a teacher dissect it and primarily focus on how none of this would have happened if it were girls that were stranded ruined that read.

But I read it again as an adult and found it much more enjoyable.
