Looking for recommendations
backstory (can be ignored): I've been reading from elementary to around grade 9 but stopped then because others things started taking up my time. Very soon I've stopped reading altogether. Because of this, I've been finding myself forgetting words often, or writing awkward sentences, and it's really annoying because I know that I've learned those words and could write way better before.
So basically I'm looking for novels that are more professional/advanced in style, but aren't too boring either. This is excluding the things you read in high school English class of course. Moreover, I probably won't have too much time to read, so quality over quantity if possible.
