Dystopian books are books that feature a dystopian society. That’s the definition. The society in Divergent is dystopian so it falls under the dystopian genre.
Some authors try to infuse their work with deeper themes and some just write things for people to purely enjoy with their brains turned off.
I only reread books that I really enjoy. It’s kind of like listening to a song I love again and again. Even though I know all the lyrics and every note, hearing it again still brings me joy.
It might not be the exact experience as the first read, but I discover something new each time.
For a second I thought I was on bookscirclejerk.
Only if I like it and plan on rereading it. I have limited shelf space and don’t want to clutter my house with books I’d never read again.
