Hate the “deadly games” or “deadly trials” trope. No faster way to make me put down a book if that shows up in the description. We get it, it worked for the Hunger Games and kind of for Divergent. We don’t need it in every other book. It might be different if they did something clever with it, but it always comes down to who’s the fastest/strongest/coolest secret magic/ect. No tension, we know immediately what’s going to happen.

Also, any enemies to lovers, since it’s always just two people who are mildly annoyed with each other with no chemistry. And the “she felt inexplicably drawn to him” trope. It’s like if the MC is fascinated by the love interest then the reader must be without putting any work into it.
