I remember teachers in my school having a poor opinion, dissuading us from reading contemporary books. I'm still not convinced on their rationale.
I don't want to read a Dickens book or Gatsby, I want to read a book that is relatable, that I can understand, that I can have fun reading. Of course, it should not be too easy in which case there is nothing to gain from it academically. For example, a relatable contemporary book might cover contemporary problems like social media, teen angst, technology - this would sit better with high school students.
We need to think: why not teach Game Of Thrones or Harry Potter? What makes them an inherently worse choice than Charles Dickens? Game of Thrones certainly has intricate characters and a nice story line.
